The COR Analyzer II is intended to assist a trained physician to analyze Computed Tomography (CT) Angiographic images. The device is not intended for use with mammography. The COR Analyzer II is specifically indicated to provide visualization of the major coronary vessels and lesions, thus assisting the physician in visualizing the coronary anatomy and pathology. COR Analyzer II has abilities for coronary vessels segmentations, abnormalities display and processing.
COR Analyzer I is a post processing software application which runs on a stand-alone Windows based work-station. The device input is Computed Tomography Angiography (CTA) set of images. The received data is displayed on the workstation screen, reviewed and selected by the operator for processing. Software provides the location and segmentation of the coronary artery tree. The software also labels the coronary arteries and displays them uniquely colored in a 3D view. The artery changes of volumes are processed and deviations from expected values are detected. When a deviation exceeds threshold value it is displayed on the 3D view.
The provided text does not contain detailed information about the acceptance criteria or a specific study proving the device meets those criteria. The 510(k) summary (K072242) for COR Analyzer II states that "Bench and clinical data demonstrate that the COR Analyzer II meets the required specifications." However, it does not provide the specific acceptance criteria, performance metrics, study design, or results of those bench and clinical studies.
Therefore, I cannot populate the table or answer most of the questions based on the provided document.
Here's a breakdown of what can be extracted and what is missing:
Information Requested | Available in Document (Y/N) | Details if available |
---|---|---|
1. Acceptance criteria table and reported performance | N | The document states, "Bench and clinical data demonstrate that the COR Analyzer II meets the required specifications," but does not list the specific specifications (acceptance criteria) or the measured performance values for comparison. |
2. Sample size and data provenance (test set) | N | No information on sample size for any test set or the provenance (country, retrospective/prospective) of data used for testing or validation is provided. |
3. Number and qualifications of experts (test set GT) | N | No information regarding experts used to establish ground truth for a test set or their qualifications. |
4. Adjudication method (test set) | N | No information on adjudication methods. |
5. MRMC comparative effectiveness study and effect size | N | The document describes a standalone post-processing software; it does not mention a multi-reader, multi-case (MRMC) comparative effectiveness study, nor does it quantify an effect size for human reader improvement with AI assistance. The device is intended to "assist a trained physician," implying human-in-the-loop, but no study details are provided. |
6. Standalone performance study | Y | The device is described as a "post processing software application which runs on a stand-alone Windows based work-station." This implies it operates independently to produce outputs, which are then reviewed by an operator. However, the document does not describe a standalone performance study with specific metrics, just that "Bench and clinical data demonstrate that the COR Analyzer II meets the required specifications." So, while the device is standalone in its operation, the details of a standalone performance study are absent. |
7. Type of ground truth used | N | No information on the type of ground truth (e.g., expert consensus, pathology, outcomes data) used for any validation or testing. |
8. Sample size for training set | N | No information on the sample size used for training the algorithm (if any machine learning model is involved, which is implied by "segmentation" and "abnormalities display and processing"). |
9. How training set ground truth was established | N | No information on how ground truth was established for a training set. |
Conclusion:
The provided 510(k) summary for K072242, COR Analyzer II, briefly mentions that bench and clinical data "demonstrate that the COR Analyzer II meets the required specifications" and that "No adverse effects have been detected." However, it does not elaborate on the specific acceptance criteria, the details of these studies, the methodologies used (like sample sizes, ground truth establishment, expert involvement, or adjudication methods), or the actual performance results. This level of detail is typically found in the full 510(k) submission not publicly available here, or in supporting documentation that would accompany such a summary for a reviewer.

- "Software Beta testing/validation will be successfully completed prior to release."
This indicates a general requirement for successful completion of tests, but no quantifiable performance metrics are reported. |
| 2. Sample size used for the test set and the data provenance | Not specified. The document mentions "Software Beta testing/validation" but does not provide details on the sample size of cases/images used in this testing, nor the country of origin of the data or whether it was retrospective or prospective. |
| 3. Number of experts used to establish the ground truth for the test set and their qualifications | Not specified. The document does not mention the use of experts to establish a ground truth for any test set or their qualifications. |
| 4. Adjudication method for the test set | Not specified. There is no mention of any adjudication method (e.g., 2+1, 3+1, none) for a test set. |
| 5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and its effect size. | No. The document does not mention an MRMC comparative effectiveness study or any effect size related to human readers improving with AI assistance. The device is a "Medical Image Processing Software" intended for clinicians to "process, analyze, review," and in the case of "CT Coronary Artery Analysis," it can "semiautomatically determine contrasted lumen boundaries, stenosis measurements," but there is no study described that compares human performance with and without this assistance. |
| 6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done | Not explicitly stated as a standalone performance evaluation with metrics. The description of "CT Coronary Artery Analysis" suggests semi-automatic functions (e.g., "semiautomatically determine contrasted lumen boundaries"), implying an algorithm-only component. However, the document does not report specific standalone performance metrics (like sensitivity, specificity, or accuracy) for these semi-automatic functions. The overall system is described as assisting clinicians in their analysis and measurements, not as a fully autonomous diagnostic tool. |
| 7. The type of ground truth used | Not specified. Since no specific performance studies or test sets with ground truth are detailed, the type of ground truth (e.g., expert consensus, pathology, outcomes data) is not mentioned. |
| 8. The sample size for the training set | Not specified. The document refers to the general software development process ("designed, developed, tested, and validated according to written procedures") but does not provide any details about a training set or its size, which would typically be associated with machine learning development. Given the 2007 submission date, the device likely predates widespread deep learning applications with distinct "training sets" as understood today. |
