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

The provided document does not explicitly state the sample size used for the non-clinical performance test set. It mentions "fifteen users," and "three users" for simultaneous connection tests for Cysware 4H, but not for the accuracy of measurements or segmentation where image data would be the primary "sample."

The data provenance is not explicitly mentioned (e.g., country of origin of data, retrospective or prospective). However, the general context is about software testing and validation against technical specifications rather than a clinical study on patient data from specific sources. The segmentation and mesh generation accuracy for Cysware 4H specifically mentions using "DICOM from CT scan source," but the origin of these CT scans is not provided.

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

This information is not explicitly provided in the non-clinical performance data section. The testing described focuses on technical specifications and usability, rather than expert-derived ground truth on clinical diagnostic images. For measures like accuracy of segmentation, there would have been a "ground truth" for comparison, but the method of establishing it and the experts involved are not detailed.

4. Adjudication Method for the Test Set

An adjudication method (e.g., 2+1, 3+1) is not mentioned as the study described is non-clinical performance testing rather than a clinical study requiring adjudication of findings (like a diagnostic accuracy study).

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 done. The document states, "Clinical testing was not required to demonstrate substantial equivalence." Therefore, no effect size of how much human readers improve with AI vs. without AI assistance is provided.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done

The performance tests for Cysware 4H's "Accuracy of Cysware 4H segmentation algorithm and Mesh generation" can be considered a standalone performance assessment of the algorithm's capability. The reported error of "lower than 1.25mm" against a ground truth (though not fully described) indicates a standalone evaluation.

7. The Type of Ground Truth Used

For the accuracy of measures (distance, angle) and segmentation accuracy of Cysware 4H, the ground truth would typically be reference measurements or segmentation derived from the input CT scan data. While the method of establishing this ground truth (e.g., expert consensus, manual annotation by a highly qualified individual, comparison to a gold standard software) is not explicitly detailed, it would inherently be a technical ground truth rather than pathological or outcomes data, as these are non-clinical hardware/software performance tests.

For Cysart 4H, the ground truth for parameters like refresh rate, autonomy, scale, connection time, display quality, and voice command efficacy are based on technical specifications and measurable operational performance criteria rather than clinical ground truth from patient data.

8. The Sample Size for the Training Set

The document does not provide information on the sample size used for the training set for any algorithms within Cysware 4H or Cysart 4H. It is stated that the software was developed, verified, and validated, implying standard software development and QA practices, but details on machine learning model training data are absent.

9. How the Ground Truth for the Training Set was Established

As no information on a training set or specific machine learning models requiring labeled training data is provided, how the ground truth for such a training set was established is not detailed.

  • . The images displayed have a refresh rate always higher than 30 frames per second, ensuring the smooth movement of the 3D objects
  • The autonomy of the HoloLens 2 when the application is open allows for the entirety of a surgery. . More specifically 1h30 without sharing the video stream and 45 minutes while sharing the video stream to a workstation connected to the same network
  • . The Cysart® 4H device reproduces the 3D objects at a scale of 1:1 and thus ensures that the 3D medical images displayed are representative of the medical images acquired from the CT scan
  • . The global time to connect to a Cysart® 4H session is no longer than 3 minutes

{15}------------------------------------------------

  • . The quality of display is sufficient for the intended use and no degradation of display occurs when adding objects or documents to an opened session
  • . The voice commands can be used in operating room as long as the ambient noise does not exceed 60dB
  • . The performance of the Microsoft® HoloLens 2 display used with Cysart® 4H is adequate and has been demonstrated by verifying: luminance, distortion, contrast, and motion-to photon latency.

9. Clinical Data

Clinical testing was not required to demonstrate substantial equivalence.

(a)
Identification. A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.(b)
