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 Story

Software application for cardiac CT image analysis; processes axial, ECG-gated dynamic CT scans acquired after intravenous contrast injection. Input data undergoes spatial and temporal filtering to reduce noise; automatic/manual detection of cardiac axes; clinician-defined regions of interest on short-axis images. Calculates myocardial blood flow, blood volume, time-to-peak, and peak enhancements. Used in clinical settings by physicians to supplement traditional visual assessment of coronary artery disease. Output displayed as composite images and quantitative metrics; assists clinical decision-making by providing perfusion data. Benefits include enhanced visualization and assessment of myocardial perfusion.

Clinical Evidence

Bench testing only. Verification and validation activities confirmed functionality against design specifications and user needs. Algorithm performance compared directly against Philips Brilliance Volume (K060937) under identical conditions, yielding similar or identical values. No clinical trial data presented.

Technological Characteristics

Software-based image processing application. Features spatio-temporal filtering, automated cardiac axes detection, and segmentation. Implements Mullani-Gould formulation for perfusion calculations. Operates on standard hardware (laptop). Connectivity/interoperability not specified beyond standard DICOM-compatible CT image input. Software developed per ISO 13485:2003 and FDA guidance.

Indications for Use

Indicated for clinicians to assist in visualization and diagnostic assessment of left ventricular myocardium using dynamic, ECG-gated CT images with intravenous contrast to provide qualitative myocardial blood flow measurements for coronary artery disease assessment.

#### 4. Device Description:

## Summary of functions of the device and its maior components

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 reqions 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 coniunction with traditional visual assessment of CT images for the assessment of coronary artery disease.

### 6. Comparison to Predicate

- The CT DMP application, Philips Brain Perfusion, and the Philips Brilliance Volume ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------(Functional CT) all generate perfusion results including blood volume, blood flow, timeto-peak and mean transit time from dynamic (serial) CT scans. The Brilliance Volume Functional CT application is built to process serial CT datasets of the body while the CT DMP application processes ECG-gated serial CT datasets of the heart and myocardium; the underlying algorithm (Mullani-Gould formulation) is the same. Additionally, the segmentation and the cardiac axes generation used in the CT DMP are similar to the one implemented in Shina CardioCT.

{6}------------------------------------------------

## Conclusion:

The Philips CT DMP application is similar to the predicate devices listed above, Philips Brain Perfusion, Philips Brilliance Volume, Shina CardioCT which have been cleared through premarketing notification. There are no significant differences between Philips CT DMP and the other predicate devices that may raise new issues of safety or effectiveness.

#### 7. Safetv

The Philips CT DMP application is manufactured in accordance with the Quality System Regulation (QSR) 21 CFR 820 and to International Standards ISO 13485:2003. Potential hazards are identified in a hazard analysis and controlled in the following manner: Software: Safety is assured by the company procedures that conform to accepted practices, including the FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices. Instructions for Use are provided with the software application for the safe and effective operation of the application by the user.

#### 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.
