Study Details for Deep-Learning Automatic Kidney Segmentation Algorithm
1. Sample sized used for the test set and the data provenance:
* Sample Size: 70 planar NM renal studies.
* Data Provenance: Acquired using GEHC systems from:
* 2 hospitals in the United States
* 1 hospital in Europe
* Nature: Retrospective (the studies were "segregated, and not used in any stage of the algorithm development," implying they were pre-existing data).
* Diversity: Served a diverse patient population including a range of ethnicities and demographics, encompassing a range of dynamic renal clinical scenarios, detection technologies, collimators, tracers, scan parameters, and patient age.
2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
* Number of Experts for Bench Testing Ground Truth: One (1).
* Qualifications: "An experienced Nuclear Medicine physician."
* Number of Experts for Clinical Testing Evaluation: Three (3) qualified U.S. readers.
* Qualifications: "Qualified U.S. readers" (further specific qualifications like years of experience or board certification are not detailed).
3. Adjudication method for the test set:
* For Bench Testing Ground Truth: The ground truth contours were reviewed and confirmed by a single experienced Nuclear Medicine physician. This suggests a form of expert consensus, but without multiple experts, it's not a multi-expert adjudication like 2+1 or 3+1. It's best described as single expert confirmation.
* For Clinical Testing: The three qualified U.S. readers independently assessed the quality of segmentation using a 4-point Likert scale. There is no mention of an adjudication process among these three readers, implying their individual assessments contributed to the overall evaluation.
4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done:
* No, a multi-reader multi-case (MRMC) comparative effectiveness study comparing human readers with AI assistance vs. without AI assistance was not explicitly described.
* The clinical testing involved multiple readers evaluating the quality of the algorithm's segmentation itself, rather than assessing their own diagnostic performance with and without AI. The focus was on the utility and acceptability of the AI output for the readers.
5. Effect size of how much human readers improve with AI vs without AI assistance:
* This information is not provided as a comparative effectiveness study was not explicitly conducted. The study assessed the acceptability of the AI's output, not the improvement in human reader performance.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
* Yes, a standalone performance evaluation of the algorithm was done. This is described as "Bench Testing" where the algorithm's generated contours were compared directly against the ground truth (GT) contours using the DICE similarity score. The "clinical testing" involved human readers evaluating the AI output, but the bench testing was algorithm-only.
7. The type of ground truth used:
* Expert Consensus: The ground truth for the bench testing (GT contours) was established by an "experienced Nuclear Medicine physician." While only one physician is mentioned, it's considered an expert-derived ground truth.
8. The sample size for the training set:
* The document does not explicitly state the sample size used for the training set of the deep learning algorithm. It only mentions that the 70 test studies "were segregated, and not used in any stage of the algorithm development," which implies they were distinct from the training data.
9. How the ground truth for the training set was established:
* The document does not explicitly state how the ground truth for the training set was established. It is only mentioned for the test set.

The CT sub-system main components include the CT gantry, PDU, and CT operator console. All components are from the commercially available GEHC Revolution Ascend CT system. The CT gantry has been adapted for use with predicate device's NM portion. CT PDU, CT Console Keyboard and CT operator console are the same as in Revolution Ascend Plus.
The provided document does not contain details about specific acceptance criteria, a study proving device performance against those criteria, or the various methodological details requested regarding sample sizes, data provenance, expert ground truth, adjudication methods, MRMC studies, or standalone performance.
The document is a 510(k) summary for the Aurora system, indicating that it is a modification of a predicate device (Discovery NM/CT 670) and incorporates components from other cleared devices. The filing emphasizes that, due to the nature of these modifications (primarily replacing a 16-slice CT with a 64-slice CT and other workflow enhancements, while the NM system is largely carried over), clinical testing was deemed unnecessary to demonstrate substantial equivalence.
The document states:
- "Because the changes associated with Aurora do not change the Indications for Use from the predicate and reference devices, and represent equivalent technological characteristics, this type of change supports using scientific, established / standardized, engineering / physics-based performance testing, without inclusion of clinical images for determining substantial equivalence."
- "Given the above information and the type and scope of changes, particularly that the NM imaging component is identical to the predicate, and the CT component is the commercially available Revolution Ascend CT system, clinical images are not included in this submission. Clinical images are not needed to demonstrate substantial equivalence."
Instead of a clinical study, the submission relies on:
- Design control testing per their quality system (21CFR 820 and ISO 13485): including Risk Analysis, Required Reviews, Design Reviews, Testing on unit level (Module verification), Integration testing (System verification), Performance testing (Verification), Safety testing (Verification), Simulated use testing (Validation).
- Conformance to standards: IEC 60601-1 and its applicable Collateral and Particular Standards (IEC 60601-1-2, 60601-1-3, 60601-2-44), as well as performance testing per NEMA NU-1.
- Additional engineering bench testing (non-clinical testing): This was performed to support substantial equivalence, demonstrate performance, and substantiate product claims. Evaluated areas included applicability of cleared lesion detectability and dose/time reduction claims, quantitation accuracy, IQ performance with low dose CT for attenuation correction, and workflow.
Therefore, the requested information cannot be extracted from this document as a clinical validation study demonstrating performance against specific acceptance criteria with human-in-the-loop or standalone performance was not part of the submission for substantial equivalence.

Clarify DL is designed to reduce image noise while maintaining contrast to enable increased Contrast-to-Noise Ratio (CNR) and Contrast Recovery Coefficient (CRC). Clarify DL is deployed within the software of the predicate Xeleris V Processing and Review System and StarGuide devices.
The provided text describes the acceptance criteria and the study conducted for Clarify DL, a deep learning-based image reconstruction method for Nuclear Medicine bone SPECT scintigraphy images.
Acceptance Criteria and Reported Device Performance
The core acceptance criteria for Clarify DL revolve around its ability to reduce image noise while maintaining contrast, thereby improving image quality. The specific metrics assessed are:
Acceptance Criterion | Reported Device Performance |
---|---|
Image Quality (Overall) | Assessed by expert NM physicians; all readers attested to acceptable diagnostic results. |
Image Resolution | Assessed by expert NM physicians; all readers attested to acceptable diagnostic results. |
Noise Level Reduction | Assessed by expert NM physicians; all readers attested to acceptable diagnostic results. Also, demonstrated by improved CNR and CRC. |
Contrast-to-Noise Ratio (CNR) | Lesion-level testing showed improvement. |
Contrast Recovery Coefficient (CRC) | Lesion-level testing showed improvement. |
Structure Similarity Index Measure (SSIM) | Image-level testing performed. |
Mean Squared Error (MSE) | Image-level testing performed. |
Peak Signal-to-Noise Ratio (PSNR) | Image-level testing performed. |
The text explicitly states that "All readers attested that their assessments of Clarify DL demonstrated acceptable diagnostic results" for overall image quality, image resolution, and noise level. Furthermore, the additional engineering bench testing "substantiated all performance claims," including improvement in CNR and CRC.
Study Details
The evaluation of Clarify DL involved both non-clinical (bench) testing and clinical reader evaluation.
Clinical Reader Evaluation (Test Set):
- Sample size used for the test set: The text mentions "clinical bone SPECT and SPECT-CT exams obtained using supported SPECT CT systems" from "11 hospitals." The exact number of exams (cases) used for the test set is not specified.
- Data provenance: The clinical exams came from "11 hospitals, including 5 US hospitals from 4 different states (i.e Ohio, Kansas, Rhode Island, and California) and 6 non-US hospitals from Europe and Asia." This indicates a prospective or retrospective collection of real-world clinical data from a diverse geographical range. The studies are described as "clinical bone SPECT and SPECT-CT exams."
- Number of experts used to establish the ground truth for the test set and their qualifications: The clinical reader evaluation involved "expert NM physicians" but the number of experts is not specified. Their qualifications are given as "expert NM physicians." No specific years of experience are provided.
- Adjudication method for the test set: The text states, "The clinical reader evaluation included review by expert NM physicians to assess overall Image Quality, Image Resolution, and Noise Level. The results of the clinical reader evaluation support the determination of substantial equivalence. All readers attested that their assessments of Clarify DL demonstrated acceptable diagnostic results." This implies a consensus or individual assessment model, but a specific adjudication method (e.g., 2+1, 3+1) is not explicitly mentioned. Given that "all readers attested," it suggests a strong agreement or individual positive assessments were sufficient.
- Multi-reader multi-case (MRMC) comparative effectiveness study: The text does not explicitly state that an MRMC comparative effectiveness study was done to compare human readers with and without AI assistance. The clinical reader evaluation assessed the Clarify DL images directly.
- Standalone (algorithm-only without human-in-the-loop performance): Yes, standalone performance was evaluated through "additional engineering bench testing". This included image-level metrics (SSIM, MSE, PSNR) and lesion-level metrics (CNR, CRC) to quantitatively assess the algorithm's performance independent of human interpretation.
- Type of ground truth used: For the clinical reader evaluation, the ground truth was expert consensus/interpretation by "expert NM physicians" regarding image quality, resolution, and noise level. For the bench testing, the "ground truth" implicitly referred to a reference image or quantitative metric against which the performance improvements (e.g., noise reduction, contrast enhancement) of Clarify DL were measured.
- Sample size for the training set: The text does not specify the sample size for the training set used for the deep learning model.
- How the ground truth for the training set was established: The text does not explicitly describe how the ground truth for the training set was established. It only states that Clarify DL uses an "OSEM-based Iterative Image Reconstruction with integrated deep learning model trained to reduce noise."

2. Sample Size for Test Set and Data Provenance
- Sample Size: The document states that the clinical reader study used "a clinically representative sample for evaluating the performance of Omni Legend's Enhanced AC option." However, the specific number of cases or patient exams in this test set is not provided.
- Data Provenance: Not explicitly stated. The document refers to "PET/CT exams acquired on Omni Legend," implying prospective acquisition on the device, but does not specify the country of origin. It also doesn't explicitly state whether the data was retrospective or prospective, though "acquired on Omni Legend" suggests prospective collection for the study.
3. Number of Experts and Qualifications for Ground Truth
- Number of Experts: The clinical reader study involved "NM physicians." The specific number of physicians is not provided.
- Qualifications of Experts: The experts were identified as "NM physicians" (Nuclear Medicine physicians). No further details on their years of experience or board certifications are given.
4. Adjudication Method for the Test Set
The document does not describe an adjudication method for the clinical reader study. It states that "Each image was read by NM physicians who provided an assessment of overall diagnostic image quality... as well as the ability of Enhanced AC to correct artifacts." This suggests individual assessments rather than a consensus or adjudicated ground truth process involving the readers themselves.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- The document describes a clinical reader study but does not explicitly state that it was an MRMC comparative effectiveness study comparing human readers with AI vs. without AI assistance. The study primarily focused on evaluating the "Enhanced AC" software option, with readers assessing diagnostic image quality and artifact correction.
- Effect Size: As it wasn't explicitly an MRMC study designed to measure human improvement with AI assistance, no effect size of human readers improving with AI vs. without AI assistance is reported. The study's conclusion is about the acceptability of the device's enhanced features.
6. Standalone Performance Study (Algorithm Only)
The document does not explicitly describe a standalone (algorithm only, without human-in-the-loop) performance study for the "Enhanced AC" option. The clinical study involved human readers assessing the images produced by the system (which includes the Enhanced AC), but it wasn't an isolated evaluation of the algorithm's output without human interpretation. The non-clinical testing included "qualitative and quantitative evaluation of PET images corrected with Enhanced AC, including demonstration of improvement in lesion quantitation," which could be considered a form of standalone evaluation, but it's not a clinical performance study.
7. Type of Ground Truth Used
For the clinical reader study, the ground truth was based on the expert assessment/consensus of NM physicians regarding the "overall diagnostic image quality" and the "ability of Enhanced AC to correct artifacts" and whether these assessments demonstrated "acceptable diagnostic results." It is not explicitly stated if pathology, outcomes data, or another objective measure was used to establish ground truth for this specific reader study. For the non-clinical testing, the "ground truth" would be established by physical measurements and phantom studies comparing results against known values as per NEMA standards.
8. Sample Size for Training Set
The document does not provide any information regarding the sample size used for training the algorithms (e.g., "Enhanced AC" or "Precision DL").
9. How Ground Truth for Training Set Was Established
The document does not provide any information on how the ground truth for any training set was established.

The user interface includes a variable height rotatable, user control panel with specialized controls, a 19-inch wide screen LCD display and a separate 12.1-inch touch panel with a resolution of 1280x800 with multi-touch capabilities.
The provided text describes a 510(k) premarket notification for the GE Vivid S60/S70 Diagnostic Ultrasound System. This type of submission relies on demonstrating substantial equivalence to legally marketed predicate devices, rather than establishing de novo safety and effectiveness through extensive clinical trials. Therefore, the information typically requested regarding acceptance criteria and a study proving the device meets those criteria will not be present in the same way as for a novel device.
Here's an analysis based on the provided document, addressing the requested information where applicable:
1. A table of acceptance criteria and the reported device performance
Since this is a 510(k) submission for substantial equivalence, the "acceptance criteria" are implicitly that the new device performs as safely and effectively as the predicate devices and shares similar technological characteristics and indications for use. There are no specific quantitative performance metrics provided as "acceptance criteria" in the sense of a novel device proving its effectiveness against a particular target. Instead, the performance is assessed by comparison to predicates.
The "reported device performance" is the statement of substantial equivalence to the predicate devices across various features and clinical applications.
Feature/Criterion | Predicate Device Performance (Implicitly Met) | Proposed Device Performance (Reported) |
---|---|---|
Intended Use | Diagnosis of specific anatomical regions and clinical applications. | Same as predicate devices, with some minor differences (e.g., Transrectal, Transvaginal, Intraoperative not listed for the new system, but many are "new" indications on the general form, implying expansion from a single predicate). |
Imaging Capabilities | B, M, Color M, Color/Power Doppler, Pulsed & CW Doppler, Combined modes, Harmonic, Coded Pulse, Realtime 3D, Multi-plane. | Same as predicate devices. |
Technological Characteristics | Fundamental scientific technology, probe array types. | Same fundamental scientific technology and probe array types. |
Safety and Effectiveness | Electrical safety, EMC, biocompatibility, acoustic output, cleaning and disinfection. | Conforms with applicable safety standards (AAMI/ANSI ES60601-1, IEC60601-1-2, IEC60601-2-37, NEMA UD 3, ISO10993-1, NEMA UD 2, ISO14971, NEMA DICOM Set). |
Track Level (FDA limits) | Track 3 | Track 3 (within FDA limits) |
Note: The tables in the document listing "N" for new indications, "P" for previously cleared, and "E" for added under appendix E show expansion of indications for different transducers compared to specific predicate clearances. The overall summary (Page 14) states the Vivid S60/S70 intended use is consistent with a range of applications, indicating a broad equivalence to multiple predicate devices.
2. Sample size used for the test set and the data provenance
No clinical test set was used for this 510(k) submission. The document explicitly states: "The subject of this premarket submission, Vivid S60/S70, did not require clinical studies to support substantial equivalence." (Page 17)
Data provenance for non-clinical tests would refer to the standards and engineering tests mentioned.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. As no clinical studies were required, no ground truth was established by experts for a test set in this submission. The "ground truth" for a 510(k) is effectively the established performance and safety of the predicate devices.
4. Adjudication method for the test set
Not applicable. No clinical test set.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This device is a diagnostic ultrasound system, not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a hardware diagnostic ultrasound system, not a standalone algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
For this 510(k) submission, the "ground truth" is the performance of the predicate devices, which have already been deemed safe and effective by the FDA. The submission demonstrates that the new device performs equivalently based on non-clinical engineering tests and comparison of technical specifications.
8. The sample size for the training set
Not applicable. This device is a standard diagnostic ultrasound system, not an AI/machine learning device that would require a training set.
9. How the ground truth for the training set was established
Not applicable. This device is a standard diagnostic ultrasound system, not an AI/machine learning device.

2. Sample Size Used for the Test Set and Data Provenance
No specific test set or clinical data (sample size, data provenance) is mentioned for evaluating the performance of the GE Vivid-i and Vivid-q BT10 system itself beyond the non-clinical tests. The submission states "Clinical Tests: None required."
For the new transducers (8C-RS, 4C-RS, SoundStar 3D 10F, AcuNav™ 8F), the document lists new indications for use that are "N = new indication (previously cleared by FDA...)" on other existing and cleared devices (GE LOGIQ Book K032477, Vivid 7 K051449, stand-alone devices K070242 by Biosense Webster, Inc., and K071234 by Siemens Medical Solutions). This implies that the safety and effectiveness for these indications with these transducers have been established in previous clearance processes and are being leveraged for this new comprehensive system. However, specific test set sizes or data provenance for these previous clearances are not detailed in this document.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications
Not applicable, as no dedicated clinical test set with ground truth establishment is described for this submission. The "Clinical Tests: None required" statement implies that existing knowledge and previous clearances were sufficient.
4. Adjudication Method for the Test Set
Not applicable, as no dedicated clinical test set with adjudication is described.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No MRMC comparative effectiveness study is mentioned. The submission relies on substantial equivalence and "Clinical Tests: None required."
6. Standalone Performance Study (Algorithm Only Without Human-in-the-Loop Performance)
The device is a diagnostic ultrasound system, not an algorithm-only device. Therefore, a standalone performance study in the context of an AI algorithm is not applicable. The device's performance is intrinsically linked to its use by a qualified physician.
7. Type of Ground Truth Used
Not explicitly stated for this particular submission, as "Clinical Tests: None required." For the previously cleared devices supporting the new indications for the transducers, ground truth would have been established through standard medical practices (e.g., expert clinical diagnosis, other imaging modalities, pathology, or surgical findings).
8. Sample Size for the Training Set
Not applicable. This document pertains to the clearance of a medical device (ultrasound system) and not the submission of an AI/ML algorithm that would typically involve a separate training set. The device's functionality is based on established ultrasound physics and signal processing, not a trained AI model in the modern sense.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no mention of an AI/ML training set.

The device is intended for use by a qualified physician for ultrasound evaluation of Fetal/Obstetrics; Abdominal/GYN; Pediatric; Small Organ (breast, testes, thyroid); Neonatal Cephalic; Adult Cephalic; Cardiac (adult and pediatric); Peripheral Vascular; Musculo-skeletal Conventional and Superficial; Urology (including prostate); Transesophageal; Transvaginal; and Intraoperative (abdominal, thoracic, and vascular).
The GE Vivid S6 are mobile ultrasound consoles having a wide assortment of electronic array transducers intended primarily for echocardiography with additional capability in vascular and general ultrasound imaging. Its intuitive user interface, high level of autooptimization along with significantly reduced size and weight maneuverable, efficient and easy to use.
The provided document K092079 is a 510(k) Premarket Notification for the GE Vivid S5 and Vivid S6 Diagnostic Ultrasound System. This submission focuses on establishing substantial equivalence to a predicate device and introducing new transducers and extended indications for use.
Crucially, the document states "Clinical Tests: None required." (Section b) 2. of Attachment B). This indicates that a study proving the device meets specific acceptance criteria, in the traditional sense of a clinical trial with performance metrics and statistical analysis, was not performed. Instead, the submission relies on the concept of substantial equivalence to a previously cleared predicate device (GE Vivid S5 and Vivid S6 Diagnostic Ultrasound System, K071985), and other previously cleared GE ultrasound systems/transducers for the new indications.
Therefore, the following information cannot be extracted from this document: acceptance criteria with reported device performance (beyond established safety standards), sample size for test set, data provenance, number of experts for ground truth, adjudication method, MRMC study details, standalone performance, or training set details.
The acceptance criteria for this submission are fundamentally satisfied by demonstrating that the modifications (new transducers and expanded indications for use) do not raise new questions of safety or effectiveness and perform as well as or better than legally marketed predicate devices.
Here's a breakdown of the available information relevant to "acceptance criteria" and how they were met in the context of a 510(k) submission focused on substantial equivalence:
1. Table of Acceptance Criteria and Reported Device Performance:
Acceptance Criteria (Implied by 510(k) for Substantial Equivalence) | Reported Device Performance (as per submission) |
---|---|
Safety: Device must conform to applicable medical device safety standards (e.g., acoustic output, biocompatibility, electrical, thermal, mechanical safety, cleaning/disinfection effectiveness). | "The device has been evaluated for acoustic output, biocompatibility, cleaning and disinfection effectiveness as well as thermal, electrical and mechanical safety, and has been found to conform with applicable medical device safety standards." (Attachment B, Section b) 1.) |
Effectiveness: Similar intended uses and operating modes to the predicate device, or demonstrated equivalence for new indications based on prior clearance of similar technology. | "The modified GE Vivid S5/S6 is of a comparable type and substantially equivalent to the current GE Vivid S5/S6. It has the same overall characteristics, key safety and effectiveness features, physical design, construction, and materials, and has the same intended uses and operating modes as the predicate device and additional software that are similar to other cleared GE Ultrasound systems." (Attachment B, Section 6.) |
Expanded Indications: New transducers and their associated clinical applications (e.g., Fetal/Obstetrics, Abdominal, Pediatric, Cardiac, Peripheral Vascular, Small Organ, Musculo-skeletal, Transesophageal, Transvaginal, Intraoperative) must be supported by previous clearances of similar technology. | For each transducer (4C-RS, 8C-RS, E8C-RS, 8L-RS, 12L-RS, 7S-RS, 10S-RS, M4S-RS, 6Tc-RS, i12L-RS, 6S-RS, 9L-RS), the Indications for Use forms clearly mark "N" for new indications, accompanied by a note stating that the transducer or application was "previously cleared" on another specified GE ultrasound system (e.g., Vivid 7 BT05 (K051449), GE LOGIQ Book Ultrasound (K032477), Vivid i/q (K082374), LOGIQ 9 (K011188), Vivid E9 (K081921), LOGIQ P5 (K060993)). "P" indicates indications previously cleared on the predicate device (K071985). |
Compliance: Design and development process conforms to 21 CFR 820 and ISO13485 quality systems. | "The design and development process of the manufacturer conforms with 21 CFR 820, and ISO13485 quality systems." (Attachment B, Section b) 3.) |
The study that proves the device meets the acceptance criteria is the 510(k) submission itself, where GE Healthcare argues for substantial equivalence based on the points above.
Missing Information (as per the document):
- Sample size used for the test set and the data provenance: Not applicable, as no clinical tests were required or performed.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience): Not applicable. The "ground truth" here is the regulatory precedent of previously cleared devices and transducers.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.
- If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This device is a diagnostic ultrasound system, not an AI-assisted diagnostic tool.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc.): The "ground truth" for the new indications is the precedent of prior FDA clearance for similar technologies and applications on other GE ultrasound systems, signifying recognized safety and effectiveness.
- The sample size for the training set: Not applicable, as no clinical tests or algorithm training were explicitly mentioned as part of this 510(k) submission for new device clearance. The device is a hardware/software system, not a machine learning model requiring a training set in the typical sense.
- How the ground truth for the training set was established: Not applicable.
