The provided text is a 510(k) summary for the Esaote Model 7340 ultrasound system upgrade (K110688). This document primarily focuses on establishing substantial equivalence to predicate devices and detailing the intended uses and technological characteristics. It does NOT contain information about specific performance acceptance criteria or detailed study results for the device's clinical performance.
Therefore, I cannot provide a table of acceptance criteria and reported device performance, nor details about sample sizes, data provenance, expert ground truth, adjudication methods, MRMC studies, or standalone algorithm performance.
However, I can extract information related to general non-clinical testing and the type of ground truth implied by regulatory standards.
Here's a breakdown of what can be inferred or explicitly stated from the document regarding the study and acceptance criteria proving device performance:
1. Table of Acceptance Criteria and Reported Device Performance:
- None explicitly stated for clinical performance. The document focuses on demonstrating substantial equivalence to predicate devices and adherence to recognized standards for safety and performance, rather than reporting on specific clinical performance metrics with acceptance criteria benchmarks.
2. Sample Size Used for the Test Set and Data Provenance:
- Not specified. The document does not describe any specific clinical test or validation set with patient data. The non-clinical testing mentioned refers to engineering verification and validation against technical standards.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
- Not applicable for clinical ground truth. Since no clinical test set is described, there's no mention of experts establishing ground truth for such a set.
4. Adjudication Method for the Test Set:
- Not applicable. No clinical test set or adjudication method is mentioned.
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:
- No MRMC study mentioned. This document predates widespread AI integration in medical devices and does not describe any such study. The device is an "Ultrasound Imaging System" with software features to assist in "venous measurements" and "venous system imaging."
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:
- Not applicable. The device is an ultrasound system with software features, not a standalone AI algorithm. It's an imaging device for physician use.
7. The Type of Ground Truth Used:
- Implied ground truth through adherence to recognized standards and substantial equivalence. The primary "proof" that the device performs as intended relies on:
- Substantial Equivalence: The device's "technological characteristics" (including clinical uses, flow profile capabilities, and safety standards) are deemed "equivalent" to those of previously cleared predicate devices (Esaote 7340, Aloka SD5500, Aloka 4000). The implication is that if the predicate devices were safe and effective, and this device is equivalent, then it is also safe and effective.
- Non-Clinical Testing against Recognized Standards: Verification and validation tests were conducted "in accordance with design controls per CFR 820.30" and designed to meet specific international and national standards. These standards (e.g., IEC 60601-1, IEC 60601-1-2, IEC 60601-2-37, ISO 10993-1, AIUM/NEMA UD-3, AIUM/NEMA UD-2) effectively serve as the "ground truth" for the device's technical and safety performance. This includes electrical safety, electromagnetic compatibility, essential performance, and acoustic output measurements.
8. The Sample Size for the Training Set:
- Not applicable. The document does not describe a machine learning algorithm with a training set. The "upgrade" consists of dedicated presets, a specific Doppler technology, and optimized probe management, which are software features, not a trainable AI model.
9. How the Ground Truth for the Training Set Was Established:
- Not applicable. As no training set for a machine learning model is mentioned, there's no information on how its ground truth would have been established.
Summary of what the document does provide:
- Device Name: Model 7340 upgrade
- Intended Use: Diagnostic general ultrasound studies across various applications (Cardiac, Peripheral Vascular, Neonatal Cephalic, Adult Cephalic, Small Organs, Musculoskeletal, Abdominal, Fetal, Transvaginal, Transrectal, Pediatric, Intraoperative, Laparoscopic, Urologic).

- Sample Size for Test Set: Not applicable for this type of submission. This 510(k) does not involve a clinical test set in the way a novel AI device might. The review is based on internal technical evaluations, compliance with standards, and comparison to a predicate device.
- Data Provenance: Not applicable. The "data" are primarily technical specifications, test reports for acoustic output, biocompatibility, etc., and a comparison matrix to the predicate device. These are internal company documents and safety standard compliance reports.
3. 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)
- Number of Experts & Qualifications: Not applicable. Ground truth, in the context of clinical studies with expert consensus, is not part of this 510(k) pathway for an ultrasound system. The "ground truth" here is adherence to engineering specifications and safety standards, and functional equivalence to the predicate device.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Adjudication Method: Not applicable. This concept pertains to resolving discrepancies in expert labeling or diagnoses in clinical studies, which were not conducted for this submission.
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
- MRMC Comparative Effectiveness Study: No. This device is a diagnostic ultrasound system, not an AI-powered image analysis tool designed to assist human readers, or a novel therapy. Therefore, an MRMC study is not relevant to its clearance.
6. If a standalone (i.e. algorithm only, without human-in-the loop performance) was done
- Standalone Performance Study: No. This device is an imaging system operated by a human physician, not an algorithm, and the concept of "standalone performance" for an algorithm is not applicable.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Type of Ground Truth: The "ground truth" in this context is the established safety and effectiveness of the predicate device (Aloka Alpha 10), and the objective measurements demonstrating that the new device meets recognized safety and performance standards (e.g., acoustic output limits, electrical safety, biocompatibility, cleaning efficacy).
8. The sample size for the training set
- Sample Size for Training Set: Not applicable. This is not an AI/machine learning device that requires a training set.
9. How the ground truth for the training set was established
- Ground Truth for Training Set Establishment: Not applicable. As this is not an AI/machine learning device, there is no training set or associated ground truth for it.
In summary: The Aloka Prosound F75 Diagnostic Ultrasound System obtained 510(k) clearance by demonstrating substantial equivalence to a predicate device (Aloka Alpha 10) through technical comparisons and compliance with recognized safety and performance standards.

The Prosound Alpha 6 Diagnostic Ultrasound System is a full feature imaging and analysis system. It consist of a mobile console that provides acquisition, processing and display capability. The user interface includes a computer type keyboard, specialized controls and a display.
This is a 510(k) premarket notification for the Aloka Prosound Alpha 6 Diagnostic Ultrasound System. It is focused on demonstrating substantial equivalence to a predicate device (Aloka SSD-4000 K040719), rather than establishing new performance criteria or efficacy through clinical trials. As such, the document does not contain the typical details of a study designed to prove a device meets specific acceptance criteria in the way an AI/CADe device approval would.
Here's an breakdown based on the provided text, highlighting the absence of information typically requested for AI/CADe approvals:
1. Table of Acceptance Criteria and Reported Device Performance
This document does not define specific performance metrics or acceptance criteria for the Aloka Prosound Alpha 6 in terms of diagnostic accuracy (e.g., sensitivity, specificity, AUC) that would typically be expected for a device proving novel diagnostic capabilities. Instead, the "acceptance criteria" are implied to be technical comparability and conformance to safety standards, and the "performance" is stated as being "substantially equivalent" to the predicate device.
Acceptance Criteria (Implied) | Reported Device Performance |
---|---|
Technical comparability to predicate device (Aloka SSD-4000 K040719) | "technically comparable and substantially equivalent" |
Same technological characteristics as predicate device | "has the same technological characteristics" |
Same key safety and effectiveness features as predicate device | "has the same key safety and effectiveness features" |
Same intended uses and basic operating modes as predicate device | "has the same intended uses and basic operating modes" |
Conformance with applicable medical device safety standards | "found to conform with applicable medical device safety standards" |
Compliance with 21 CFR 820, ISO 9001:2000, ISO 13485 quality systems | "confirms with 21 CFR 820, ISO 9001:2000 and ISO 13485 quality systems" |
Safe and effective performance (as per diagnostic ultrasound history) | "Diagnostic ultrasound has accumulated a long history of safe and effectiveness performance." |
2. Sample Size Used for the Test Set and Data Provenance
The document explicitly states "None Required" for clinical tests for the purpose of demonstrating substantial equivalence. Therefore, there is no test set, sample size, or data provenance relevant to proving diagnostic performance against predefined acceptance criteria. Clinical practices, FDA guidelines, and established patient examination methods are cited as sufficient to confirm intended uses and features.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
Since no clinical test set was used to assess diagnostic performance of the new device itself, there were no experts used to establish ground truth in this context. The "ground truth" for the substantial equivalence claim relies on the established safety and effectiveness of the predicate device and the general understanding of diagnostic ultrasound.
4. Adjudication Method for the Test Set
As there was no clinical test set, there was no adjudication method employed.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not conducted or described in this document. This submission focuses on substantial equivalence based on technical specifications and established safety, not on improving human reader performance with or without AI assistance.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done
The Aloka Prosound Alpha 6 is a diagnostic ultrasound system, not an AI or algorithm-only device. Therefore, a standalone algorithm performance study was not applicable and not conducted. It's a medical imaging hardware and software system used by humans.
7. The Type of Ground Truth Used
The concept of "ground truth" as it applies to diagnostic accuracy for a new device's performance is not directly addressed. Instead, the ground truth for this 510(k) submission is the established safety and effectiveness record of the predicate device (Aloka SSD-4000) and general diagnostic ultrasound technology. The "truth" is that its technical characteristics and intended uses align with a device already cleared by the FDA, implying similar safety and effectiveness.
8. The Sample Size for the Training Set
The Aloka Prosound Alpha 6 is a traditional ultrasound system, not an AI/ML device that requires a training set in the computational sense. Therefore, there is no training set mentioned or applicable.
9. How the Ground Truth for the Training Set was Established
As there is no training set for an AI/ML algorithm, this question is not applicable.

(15 days)
Diagnostic ultrasound imaging or fluid flow analysis of the human body as follows: Fetal, Abdominal, Intraoperative (liver, pancreas and gall bladder), Intraoperative Neurological, Pediatric, Small Organ (breast, testes and thyroid), Neonatal Cephalic, Adult Cephalic, Cardiac, Transesophageal, Transrectal, Transvaginal, Peripheral Vascular, Laparoscopic, Musculo-skeletal Conventional, Musculo-skeletal Superficial. Mixed mode operation includes B/M, B/PWD, M/CD, B/CD/PWD.
The Aloka SSD-3500 functions in the same manner as other diagnostic ultrasound devices. High frequency sound waves are transmitted into the body by a piezo-electric transducer. In the body, differences in the acoustic impedance of different tissues reflect a certain amount of the ultrasound energy back to the transducer, where it is transmitted via the probe cable to the system console and processed into an image. The Aloka SSD-3500 transducer can also use the Doppler shift of sound reflected from moving tissues (blood) to detect and display flow.
The Aloka Model SSD-3500 Diagnostic Ultrasound System is substantially equivalent to previously cleared predicate devices (Aloka SSD-4000 and SSD-5500). The submission focuses on demonstrating substantial equivalence rather than presenting a performance study with specific acceptance criteria that would typically be seen for novel devices or AI/CAD systems.
Therefore, the "acceptance criteria" for this submission are primarily met by demonstrating similarity in:
- Intended Use: The device is indicated for the same diagnostic ultrasound applications as the predicate devices.
- Technological Characteristics: The device utilizes essentially the same technologies for imaging, Doppler functions, and signal processing.
- Method of Use: The device has the same method of use as the predicate devices.
- Safety Standards: The device complies with acoustic power output levels below FDA maximums, uses patient contact materials evaluated by the same standards, and meets electrical and physical safety standards (NEMA-UD2: 1992, AUM 1994, IEC-60601-1, UL 2601-1, ISO10993-1:1997).
Since this is a substantial equivalence submission for an ultrasound system, not an AI/CADe device, the typical elements of an AI/CADe performance study (test set, ground truth, expert readers, MRMC study, standalone performance) are not applicable or explicitly provided in the document. The "study" proving acceptance criteria is the comparison to predicates and adherence to established safety standards for diagnostic ultrasound equipment.

- Not applicable. Adjudication methods are used in AI/CADe studies to establish ground truth from multiple expert opinions.
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:
- No. An MRMC comparative effectiveness study is designed to assess the impact of an AI/CADe device on human reader performance. This submission is for a diagnostic ultrasound system and does not involve AI assistance for image interpretation.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- No. This device is a diagnostic ultrasound system, which inherently involves a human operator to acquire and interpret images. There is no "algorithm only" performance reported in the context of AI/CADe.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Not applicable in the context of a clinical performance study using a test set. The validation of the device relies on demonstrating performance within acceptable limits as defined by engineering standards and functional equivalence to predicate devices, rather than a clinical ground truth regarding disease presence. Performance is measured in terms of image quality, acoustic output, and other technical specifications.
8. The sample size for the training set:
- Not applicable. This device is not an AI/CADe system where a "training set" would be used to develop an algorithm.
9. How the ground truth for the training set was established:
- Not applicable for the same reason as above.

The Aloka SSD-1400 is not indicated for ophthalmic applications.
Diagnostic ultrasound imaging or fluid flow analysis of the human body as follows: (followed by tables listing specific clinical applications and modes of operation for the system and various transducers).
The SSD-1000 makes no changes to the indications for use, the ultrasound generator, transducer(s), controls, and signal processing technologies. There are no new system functions added, significant new clinical information provided or significant claims of added effectiveness. In addition, clinical applications/modes of operation provide no new significant interpretation of predicate device; the SSD-1400.
The Aloka SSD-1000 Diagnostic Ultrasound System provides diagnostic ultrasound imaging and fluid flow analysis for various clinical applications. The study provided does not detail specific quantitative acceptance criteria or a study designed to prove these criteria were met. Instead, the document establishes substantial equivalence to a predicate device (SSD-1400, K972465) by demonstrating that the SSD-1000 makes no changes to the indications for use, ultrasound generator, transducers, controls, and signal processing technologies. No new system functions, significant new clinical information, or claims of added effectiveness are noted.
The acceptance criteria are implicitly based on the substantial equivalence of the new device's capabilities to the cleared predicate device. The performance of the device is reported through a list of clinical applications and modes of operation for which the device and its various transducers are intended.

2. Sample size used for the test set and the data provenance:
The provided 510(k) summary does not mention a specific test set or data provenance from a prospective or retrospective study for verifying performance against acceptance criteria. The approval is based on substantial equivalence to a predicate device. A post-market surveillance requirement is mentioned in page 3 of the document, requesting "acoustic output measurements based on production line devices" prior to shipping the first device, but this is related to safety and manufacturing compliance rather than clinical performance evaluation.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
This information is not provided in the document. The approval is based on substantial equivalence, not on a new clinical study requiring ground truth establishment by experts.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
No adjudication method is mentioned, as there is no specific test set described in the context of clinical performance evaluation.
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:
No MRMC comparative effectiveness study is mentioned. This device is a diagnostic ultrasound system, not an AI-powered device, so human reader improvement with AI assistance is not applicable in this context.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable, as this is a medical device for imaging, not an algorithm, and it requires a human operator for its intended use.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
Not applicable. The filing is based on substantial equivalence to a predicate device, meaning its performance characteristics are deemed equivalent to a device already on the market, rather than requiring new ground truth data for novel claims.
8. The sample size for the training set:
Not applicable, as this is a medical device, not a machine learning algorithm that requires a training set.
9. How the ground truth for the training set was established:
Not applicable, for the same reason as above.
