The IQQA-Guide System is a stereotactic accessory for Computed Tomography (CT). It displays simulated image of interventional instruments (such as biopsy needle, ablation needle, probe) on a computer monitor that also shows an imaging-based 3D model of the patient anatomy, and the current and the projected future path of the interventional instruments.
The system supports the imaging-based model derived from physician's confirmed segmentation results of patient's image scans, including intra-operative CT, pre-procedural CT, and CT or MR previously acquired before surgical procedures. Additionally, overlaying ultrasound images (when available) may be displayed with the model of patient anatomy.
The system supports a workflow based on automated image registrations of spatial mapping from one image space to another image space, or from image space to physical space. Physician may interactively adjust and confirm registration results, and evaluate 3D visualization and quantitative information in terms of distance, size, and spatial location associated with patient anatomy and instruments.
The system is intended for intra-operative guidance for surgical procedures. It is intended for use by trained physicians in clinical intervention and for structures where imaging is currently used for visualizing such procedures.

- Simulated images: An unspecified number of simulated images described as containing "ellipsoid, crescent, and cylinder shapes."
- Retrospective clinical patient studies: An unspecified number of "clinical patient studies" of CT and MR for thoracic, abdominal, and pelvic body parts.
- Phantom image pairs: An unspecified number of "phantom image pairs scanned at different times with different positioning and orientations."
- Patient studies with synthetic deformations: An unspecified number of "patient studies with synthetic deformations."
- Retrospective patient studies for registration: An unspecified number of "retrospective patient studies that are scanned at different times during clinical practice."
- Data Provenance:
- Simulated images: Artificially generated (simulated).
- Clinical Patient Studies (for intra-observer consistency): Retrospective, specific country of origin not mentioned, but described as "clinical patient studies."
- Phantom Studies (for registration): Acquired from physical phantoms, specific country/institution not mentioned.
- Patient Studies (for automated and interactive registration): Retrospective, specific country of origin not mentioned, but described as "patient studies."
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- Number of Experts:
- For intra-observer consistency in volume measurement validation, "two physicians" were used.
- For clinical site validation/feedback, "physicians" at "two clinical sites" were involved, but the specific number involved in establishing ground truth for the performance metrics is not detailed.
- Qualifications of Experts: The document states "physicians" were used. No further details about their specific qualifications (e.g., specialty, years of experience, subspecialty) are provided.
4. Adjudication Method for the Test Set
- Intra-observer consistency: Implies a comparison between the measurements of two physicians, not necessarily an adjudication to establish a "ground truth" but rather to assess agreement between human operators using the device.
- For other tests where "ground truth" is mentioned (e.g., volumetric measurement accuracy on simulated images, registration error relating to phantom studies), the method of establishing this ground truth is not specified as an adjudication process. The ground truth for simulated images would be known by design. For phantom studies, it's typically based on physical measurements or precise setup parameters.
- No specific adjudication method like "2+1" or "3+1" is described.
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 described in the provided text. The document focuses on the performance of the software's sub-components (segmentation, measurement, registration) and intra-observer consistency when physicians use the tools.
- There is no mention of comparing human readers with AI assistance versus without AI assistance to measure an effect size of improvement. The device is positioned as a tool to support physician evaluation, not explicitly to replace or augment their accuracy in a comparative study.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
- Yes, partially.
- The "Volumetric Measurement Accuracy" test on simulated images would likely represent a standalone performance evaluation against a known ground truth.
- The "Initial Automated Registration Error" on patient studies with synthetic deformations also appears to be a standalone measurement of the algorithm's performance before any interactive adjustment.
- However, other tests, like "Intra-observer Consistency" and "Interactive Registration Error," specifically involve human interaction with the device.
7. The Type of Ground Truth Used
- Simulated Images: "Ground truth" was established by the design of the simulated objects (ellipsoid, crescent, cylinder shapes).
- Phantom Studies (for registration): "Ground truth" would likely be derived from the known physical properties or precise measurements of the phantom and its setup.
- For clinical patient studies (intra-observer consistency and general registration performance), the "ground truth" for the observed differences is not explicitly described as pathology or outcomes data. Instead, the evaluations focus on consistency between human measurements or the accuracy of the software against a reference (which for patient studies might be a manual measurement considered as the reference standard, though not specified).
8. The Sample Size for the Training Set
- Not provided. The document describes validation and testing, but it does not mention the sample size used for training the algorithms within the IQQA-BodyImaging Software.
9. How the Ground Truth for the Training Set Was Established
- Not provided. Since the training set sample size is not mentioned, neither is the method for establishing its ground truth.

1. Acceptance Criteria and Device Performance:
The provided document does not explicitly list acceptance criteria in a table format with corresponding reported device performance values. It states that "Test results support the conclusion that actual device performance satisfies the design intent." However, it does not quantify what that "design intent" or "acceptance criteria" actually were.
What is provided is a general statement about the successful outcome of testing and the fulfillment of the intended use, and the FDA's concurrence that the device is substantially equivalent to predicate devices. More specific performance metrics and their comparison to acceptance thresholds are not detailed in this summary.
2. Sample Size and Data Provenance for the Test Set:
The document states: "EDDA Technology has conducted software testing at two clinical sites." However, it does not specify the sample size (number of cases or patients) used for this clinical testing.
The data provenance is implicitly retrospective as it mentions "physicians use the v2.0 software application to review multiphase CT and MR images of the liver". The document does not specify the country of origin of the data.
3. Number and Qualifications of Experts for Ground Truth:
The document states: "The purpose of the testing is to have physicians use the v2.0 software application to review multiphase CT and MR images of the liver... and provide feedback along the line of the intended use of the system."
It does not specify the number of physicians or their specific qualifications (e.g., years of experience, subspecialty in radiology) used to establish ground truth or provide feedback. It only refers to them as "physicians."
4. Adjudication Method for the Test Set:
The document does not describe any specific adjudication method used for the test set (e.g., 2+1, 3+1 consensus). It only mentions that physicians used the software, validated major functionalities, and provided feedback. This suggests a less formal "feedback" approach rather than a structured adjudication process for ground truth establishment.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
A MRMC comparative effectiveness study was not explicitly described in the provided document. The study described was focused on physicians using the software to validate functionalities and provide feedback, not on comparing human reader performance with and without AI assistance to quantify an effect size.
6. Standalone (Algorithm Only) Performance Study:
The document does not describe a standalone performance study where the algorithm's performance was evaluated without human interaction. The clinical testing involved "physicians use the v2.0 software application," implying a human-in-the-loop scenario. The preceding software testing mentioned ("Software testing and validation were done according to written test protocols") likely refers to internal functional and verification testing rather than performance validation against a clinical ground truth in a standalone mode.
7. Type of Ground Truth Used:
The ground truth for the clinical testing appears to be based on physician-identified findings and evaluations. The document states that "physicians use the v2.0 software application to review multiphase CT and MR images... and provide feedback along the line of the intended use of the system." This suggests that the "ground truth" was established by the interpreting physicians and their clinical assessment/feedback, rather than a definitive, independent source like pathology or long-term outcomes data.
8. Sample Size for the Training Set:
The document does not specify the sample size used for the training set. The summary focuses on the validation/testing activities.
9. Ground Truth Establishment for the Training Set:
The document does not describe how the ground truth for the training set was established. This information is typically proprietary and often not included in 510(k) summaries.

The provided text is a 510(k) summary for the EDDA Technology IQQA-Liver Software. While it describes the device's intended use, comparison to predicate devices, and general statements about testing, it does not contain detailed information about specific acceptance criteria and a study proving those criteria are met.
The document states:
- "Testing was performed according to internal company procedures. Software testing and validation were done according to written test protocols established before testing was conducted. Test results were reviewed by designated technical professionals before software proceeded to release. Test results support the conclusion that actual device performance satisfies the design intent."
This is a general statement of compliance, but it does not provide the quantitative acceptance criteria, the details of a study, or the specific performance metrics.
Therefore, I cannot populate the table or answer most of your detailed questions based on the provided text.
Here's what can be inferred or explicitly stated from the document, though it falls short of your request for specific acceptance criteria and study details:
1. A table of acceptance criteria and the reported device performance
- Cannot be provided. The document does not list specific, quantifiable acceptance criteria or reported performance results (e.g., accuracy, precision, sensitivity, specificity, or error rates for segmentation, volume analysis, etc.). It only broadly claims that "actual device performance satisfies the design intent."
2. Sample size used for the test set and the data provenance
- Cannot be determined. The document does not specify the sample size of the test set or the origin (country, retrospective/prospective) of the data used for testing.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Cannot be determined. The document does not mention the use of experts for establishing ground truth or their qualifications. Given the device's function involves physician-identified lesions and analysis tools, it's implied that physician input is central, but no formal ground truth establishment process is described for testing.
4. Adjudication method for the test set
- Cannot be determined. The document does not describe any adjudication methods.
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
- Cannot be determined. The document does not mention a multi-reader, multi-case (MRMC) study or any comparative effectiveness study measuring human reader improvement with or without AI assistance. The device is described as "supporting physicians" but not necessarily replacing or directly augmenting their diagnostic accuracy in a quantifiable comparison presented here.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- Cannot be determined. The document explicitly states the device is "designed for use by trained physicians" and that "Physicians make all final patient management decisions." This framework suggests a human-in-the-loop design, but it doesn't preclude standalone testing of individual algorithms within the software, though such testing is not detailed.
7. The type of ground truth used
- Cannot be determined with certainty. The software relies on "physician-identified liver lesions" and "interactive segmentation of physician-identified lesions using user input of seed points." This suggests that "expert consensus" or "physician input" forms the basis of the data the software processes, but it does not describe how a ground truth was established for testing or validation purposes. It's likely that a clinical reference (e.g., pathology, clinical follow-up) would have been used for any robust validation, but this is not stated.
8. The sample size for the training set
- Cannot be determined. The document focuses on the device's intended use and comparison to predicates, not on its development or training process.
9. How the ground truth for the training set was established
- Cannot be determined. Similar to point 8, this information is not present in the provided 510(k) summary.
In summary, the provided 510(k) document is a regulatory summary focused on substantial equivalence to predicate devices and does not detail the technical performance studies and acceptance criteria typically found in clinical trial reports or more comprehensive technical files.
