Intended Use
The CT Dynamic Myocardial Perfusion (CT DMP) application is intended to assist clinicians in the visualization and diagnostic assessment of cardiac images focusing on the left ventricular myocardium: specifically providing qualitative myocardial blood flow measurements for CT images. The application supports axial, ECG gated CT images, consisting of multiple time shots within the same study of the same myocardial region over time (i.e., dynamic CT scans), after the injection of intravenous contrast. The application displays the results as a composite (single image that is calculated from a set of time course images at a single location) image.
Device Description
The CT Dynamic Myocardial Perfusion (DMP) Application is intended for visualization and assessment of cardiac images focusing on the left ventricular myocardium: specifically providing qualitative myocardial blood flow measurements for CT images. The application supports axial, ECG gated CT images, consisting of multiple time shots within the same study of the same myocardial region over time. The application provides visualization and measurement tools for qualitative visualization and assessment of the input data. The data upon loading is first registered and filtered in the spatial and the temporal domain to reduce any noise variations, following which, the cardiac axes of the heart are detected using the automatic and manual tools. The images are displayed in the short-axis format and the clinician can then define the regions of interest using manual tools upon the short axis format. The software calculates measurements of myocardial blood flow, myocardial blood volume, time to peak, and peak enhancements, and provides tools for the clinician to assess these results. The user may save the results. The clinician retains the ultimate responsibility for making the pertinent assessment based on their standard practices and visual assessment of the myocardial perfusion CT images. The qualitative assessment is to be used in conjunction with traditional visual assessment of CT images for the assessment of coronary artery disease. The different components in the CT DMP application are: CT DMP Models: . CT DMPViewingModel - Main model in the application. Holds all the relevant data for results: volume, tissue, etc. CT DMP Algorithms: . Artery Automatic Detection . Segmentation . Cardiac Axes . Spatio-temporal filtering .

More Information

No
The summary describes image processing algorithms (registration, filtering, segmentation, detection) and calculation of quantitative metrics, but does not mention AI or ML. The performance evaluation focuses on verification against specifications and comparison to a predicate device, not on training or testing of an AI/ML model.

No

This device is intended to assist clinicians in visualization and diagnostic assessment by providing qualitative myocardial blood flow measurements for CT images. It does not directly treat or prevent any condition.

Yes

The "Intended Use / Indications for Use" section explicitly states that the application is "intended to assist clinicians in the visualization and diagnostic assessment of cardiac images." It further specifies its purpose is "specifically providing qualitative myocardial blood flow measurements for CT images," which are used in diagnosis. The "Device Description" also mentions "assessment of cardiac images" and calculating measurements like "myocardial blood flow" for assessment.

Yes

The device description explicitly states it is an "Application" and details software components (Models, Algorithms, Controllers, Tools). While it processes CT images, it does not describe any hardware components that are part of the device itself. The validation mentions being performed on a laptop meeting HW requirements, implying the device is the software running on standard hardware, not the hardware itself.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body (like blood, urine, or tissue) to detect diseases, conditions, or infections.
  • Device Function: The CT Dynamic Myocardial Perfusion (CT DMP) application processes and analyzes images of the heart obtained from a CT scanner. It does not perform tests on biological samples.
  • Intended Use: The intended use is to assist clinicians in the visualization and diagnostic assessment of cardiac images, specifically providing qualitative myocardial blood flow measurements from CT images. This is image analysis, not in vitro testing.
  • Device Description: The description details image processing techniques (registration, filtering, segmentation, calculation of perfusion maps) applied to CT images. It does not mention any handling or analysis of biological specimens.

Therefore, while this device is a medical device used for diagnostic purposes, it falls under the category of medical image processing software rather than an In Vitro Diagnostic device.

8. Performance Testing Summary

Verification Activities:

Verification was conducted to provide objective evidence that the application met its design specifications. This was done by testing the function and implementation of the application as well as risk management file.

The narrative below provides a brief summary of the verification and validation activities. The details of the testing including test plans and reports can be found in Section 018 of this submission.

The verification plan for the CT DMP Application (DMP-007) outlines the verification activities conducted to verify the function of the application and product's stability. Testing included full functionality of CT DMP application and risk management file (RMF) related to defined requirements. The requirements for CT DMP are traced to the clinical DRS and detailed test scenarios were written and accordingly the verification was conducted [DMP-005]. CT DMP verification included sanity tests which gave an overview of the application maturity for each build, critical tests which included tests of the main features and workflow and RMF tests which in general check calculations, measurements, patient details and information and other scenarios which might lead to misdiagnosis. CT DMP Algorithm implementation was evaluated through a direct comparison of values obtained by comparing the performance of CT DMP and the Philips predicate, Brilliance Volume K060987, under the same use conditions. The values obtained in the comparison were similar or the same under all test conditions.

Full functionality testing included all CT DMP functionality cases and covered all of the detailed requirements which provided us with assurance that the tested features work as required. Verification also covered the defect fixes of CT DMP.

All the planned activities for verification have been completed.

7

Validation Activities:

The CT DMP validation activities, as documented in the DMP Validation Plan (DMP-009), were performed to provide objective evidence that the CT DMP Application meets the intended use and defined customer needs outlined in the DRS DMP-002.

Validation was performed externally to Philips on a laptop which met the HW requirements. The results of the validation activities found in the Validation Report for DMP (DMP-0010) confirms that the CT DMP Application meets user needs and intended uses.

Based on the above considerations, it is Philips's opinion that the results of the verification and validation testing and the results of the risk analysis demonstrates safety and effectiveness of the Philips CT DMP Application and that it is substantially equivalent to the predicate devices documented above.

Information on security and privacy attributes of the CT DMP Application are found in document ISP-600-P3-0021-01 which can be found in Section 021.
