SeeMor™ 5.0 software program should be used for the transfer, display and image manipulation of multimodality diagnostic medical images and for the image than backprojection reconstruction reconstruction of SPECT & PET gated and ungated myocardial perfusion data.

The SeeMor™ 5.0 medical viewing application is used for transfer and viewing diagnostic medical images. The program provides the capabilities of manipulating the images being displayed with the command options including: clipping, window/level adjustment, magnification, pan, relate, add, delete, next, cine, lock, select, view, flip vertical/horizontal, set color table, orthogonal view reconstruction, cascade, tile, and reset. The ReconTool™ processing application within Seemor™ 5.0 can be used to reorient and apply tomographic reconstruction to SPECT & PET gated and ungated myocardial perfusion image data sets.

Acceptance Criteria and Study for SeeMor™ 5.0 (K041132)

Based on the provided text, the SeeMor™ 5.0 device is a medical imaging display and processing program. The study described focuses on proving its "safety and effectiveness" for its intended use, which primarily involves the display, manipulation, reorientation, and tomographic reconstruction of SPECT & PET gated and ungated myocardial perfusion image data sets. It's explicitly stated that the device "does not provide any interpretive output other than the display of the images."

Due to the nature of the device (a display and reconstruction tool rather than an AI diagnostic aid), the typical metrics for AI performance (e.g., sensitivity, specificity, AUC) and an MRMC comparative effectiveness study are not explicitly mentioned in the provided text. The study primarily validates the functionality and accuracy of the image processing aspect.

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state quantitative acceptance criteria or precise performance metrics in the format of "X% accuracy" or "Y level of error." Instead, it relies on the successful completion of "initial design, coding, debugging, testing, and in-house validation" to demonstrate safety and effectiveness. The effectiveness is judged by the ability to correctly reorient and reconstruct images, as observed in the trial.

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size: 20 patients.
• Data Provenance: Not explicitly stated, but implied to be retrospective as it refers to an "evaluation of 20 patients" in an "in-house trial validation." The country of origin is not mentioned.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

• Number of Experts: Not specified.
• Qualifications of Experts: Not specified. The document states that "The final responsibility for interpretation of the study lies with the physician," implying that physician judgment would be the ultimate arbiter, but doesn't detail their specific role in establishing ground truth for the technical effectiveness of the reconstruction.

4. Adjudication Method for the Test Set

• Adjudication Method: Not specified. Given the nature of the device (a display and reconstruction tool), the "ground truth" for its effectiveness would likely be the visual correctness of the reconstructed images compared to expected outputs, rather than a diagnostic consensus among clinicians for a specific diagnosis.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• MRMC Study Done? No. The document does not describe an MRMC study comparing human readers with and without AI assistance. This is consistent with the device's function as a display and processing tool, not a diagnostic AI.

6. Standalone (Algorithm Only) Performance

• Standalone Study Done? Yes, in a sense. The "in-house trial validation" assessed the functionality and output of the SeeMor™ 5.0 program (including ReconTool™) on its own, without human intervention in the image processing itself, although human review was necessary to verify its effectiveness. The device's "effectiveness" was based on its ability to produce accurate reconstructed images.

7. Type of Ground Truth Used

• Type of Ground Truth: Implied to be technical correctness/visual fidelity of the reconstructed images. The effectiveness was assessed on whether the program successfully performed the requested reorientation and tomographic reconstruction of SPECT & PET data, likely validated by visual inspection and comparison to expected outputs or existing proven methods. It is not pathology, expert consensus on diagnosis, or outcomes data, as the device does not provide diagnostic interpretations.

8. Sample Size for the Training Set

• Sample Size: Not applicable/not specified. The device is a software application for image display and reconstruction, not an AI model that undergoes a "training set" in the machine learning sense. Its development involved "initial design, coding, debugging, testing, and in-house validation," which are typical software development stages, not AI model training.

9. How Ground Truth for the Training Set Was Established

• How Ground Truth Was Established: Not applicable. As discussed above, there is no "training set" in the AI sense for this device. Its functionalities are based on established image processing algorithms.
