To demonstrate the coronary tracing quality improvement for subject device syngo.CT Coronary Analysis, quantitative performance testing was conducted to test the following functions: - Centeredness of the Centerlines ● - Tracing of branches ● - Coverage of Centerlines . As part of this testing, a sampling of centerlines from a predetermined number of datasets were evaluated. To test for accuracy of centeredness, the derived centerlines were assessed in comparison to the predicate device to demonstrate an improvement in the ability of the subject device application to more accurately follow the vessels in the lumen. Testing for the tracing of branches and coverage of centerlines was conducted on branches that were considered both clinically relevant and clinically irrelevant to assess sensitivity and specificity of branch tracing and coverage. The results of this test demonstrated an increased sensitivity and specificity and improved vessel coverage for the subject device tracing feature in comparison to the predicate device. To demonstrate the functionality of the vessel tracing quality improvement for subject device syngo.CT Vascular Analysis, the detection rate of a predetermined set of vessels was evaluated to determine whether a vessel was successfully traced if a vessel was expected based on activation of the algorithm. The result of this test demonstrated that the subject device had a higher level of traced vessels in comparison to the predicate device, which supports an improvement of vessel tracing quality in comparison to the predicate device. #### Software Verification and Validation Software Documentation for a Moderate Level of Concern software per FDA's Guidance Document "Guidance for the Content of Premarket Submissions for Software in Medical Devices" issued on May 11, 2005 is also included as part of this submission.

The word is written in all capital letters. The color of the text is a light blue or turquoise. # VIII. Conclusions The subject devices have the same intended use as the predicate devices. The technological characteristics such as image visualization, operating platform, and image manipulation remain unchanged from the predicate device. The predicate devices were cleared based on non-clinical testing including verification and validation testing. The results of these tests demonstrate that the predicate devices are adequate for the intended use. The subject devices are also tested using the same methods and workflows as used for the predicate devices. The comparison of technological characteristics, non-clinical performance data, and software validation included in this submission demonstrates that the subject device is as safe and effective when compared to the predicate devices that are currently marketed for the same intended use. Since both devices were tested using the same methods, Siemens believes that the data generated from the subject devices syngo.CT Coronary Analysis and syngo.CT Vascular Analysis testing supports a finding of substantial equivalence.
