No
The summary explicitly states "Mentions AI, DNN, or ML: Not Found" and the description focuses on post-processing and visualization tools without mentioning any learning or adaptive capabilities.
No
The device is described as software for advanced visualization, measurement, and evaluation of CT images, designed to support radiologists and physicians in diagnosis and evaluation, not for treating or providing therapy.
Yes
The device is described as software applications for "advanced visualization, measurement, and evaluation" of CT images, designed to "support the radiologists and physicians" in the "evaluation of perfusion of organs and tumors," "detection of bone lesions," and "evaluation of coronary lesions," among other medical conditions. These functions directly involve the interpretation of medical images to identify or assess diseases, which is a core function of a diagnostic device.
Yes
The device is explicitly described as "syngo based post-processing software applications" and a "combination of fourteen (14) medical devices which are handled as features / functionalities within syngo.CT Applications." The description focuses solely on software functionalities for viewing and evaluating CT images provided by a separate CT diagnostic device. There is no mention of accompanying hardware components included with the device itself.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use describes the software as a tool for advanced visualization, measurement, and evaluation of CT images for specific body regions. This is a post-processing tool for medical images, not a device that performs tests on biological samples (like blood, urine, or tissue) to diagnose or monitor a condition.
- Device Description: The description explicitly states it's "syngo based post-processing software applications to be used for viewing and evaluating CT images provided by a CT diagnostic device." This reinforces its role in image analysis, not in vitro testing.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or any other components typically associated with in vitro diagnostics.
The device is clearly a medical image analysis software intended to aid physicians in interpreting CT scans.

8. Performance Data
The following performance data were provided in support of the substantial equivalence determination.
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 Contained in Medical Devices" issued on May 11, 2005 is also included as part of this submission. The performance data demonstrates continued conformance with special controls for medical devices containing software. The Risk Analysis was completed, and risk control implemented to mitigate identified hazards. The testing supports that all software specifications have met the acceptance criteria. Testing for verification and validation support the claim of substantial equivalence.

9. Conclusion
The fundamental scientific technology and technological characteristics are the same as the predicate device and reference device. The built-in applications in the subject device remain unchanged as the built-in ones in the predicate device except the application syngo.CT Pulmo 3D which includes the changes as shown in the comparison table. The additional bundling of syngo.CT CaScoring to the subject device and the minor improvements and enhancements do not raise questions of safety and efficacy since the changes do not introduce any new clinical algorithms/features and they do not change the performance of subject device significantly.
The result of all testing conducted was found acceptable to support the claim of substantial equivalence. The comparison of technological characteristics and software validation demonstrates that the subject device is as safe and effective when compared to the predicate device that is currently marketed for the same intended use.
For the subject device, syngo.CT Applications, Siemens used the same testing with the same workflows as used to clear the predicate devices. Siemens considers synqo.CT Applications to be as safe, as effective and with performance substantially equivalent to the commercially available predicate device.
Therefore, Siemens believes that the subject device, the syngo.CT Applications does not raise new questions of safety and effectiveness and is substantially equivalent to the predicate device.
