The summary describes a standard CT scanner with image reconstruction and post-processing features, but there is no mention of AI or ML algorithms being used for image analysis, interpretation, or any other function. The performance studies focus on the functionality of specific post-processing features, not on the performance of an AI/ML model.
No.
The device is described as a Computed Tomography X-ray System intended to produce cross-sectional images of the body for diagnostic purposes, not for treating diseases or conditions.
Yes
The device is described as "intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data," which are then used in post-processing applications for "evaluation" and features like "FAST DE Result evaluation," indicating its role in providing information for diagnostic purposes.
No
The device description explicitly states it is a "Computed Tomography X-ray System" which includes hardware components (rotating tube-detector system, computer system delivered with the scanner) in addition to the software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use is to "produce cross-sectional images of the body by computer reconstruction of xray transmission data." This describes an imaging device used to visualize internal structures of the body.
- Device Description: The device is described as a "Computed Tomography X-ray System." CT scanners are imaging devices, not devices that analyze samples taken from the body.
- No mention of analyzing biological samples: The description focuses on acquiring and processing X-ray data to create images. There is no mention of analyzing blood, urine, tissue, or any other biological sample.
- Focus on image processing: While the device performs image reconstruction and post-processing, this is done on the acquired X-ray data, not on biological samples.
IVD devices are specifically designed to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device's function is to create images of the body itself using X-rays.

Device Description
The Siemens SOMATOM Definition AS/AS* and SOMATOM Definition Edge equipped with syngo CT VA48 are Computed Tomography X- ray Systems. which feature a continuously rotating tube-detector system and functions according to the fan beam principle. The SOMATOM Definition AS/ AS* and SOMATOM Definition Edge produce CT images in DICOM format, which can be used by post-processing applications commercially distributed by Siemens and other vendors.
The system software is a command-based program used for patient management, data management, X-ray scan control, image reconstruction, and image archive/evaluation. The version of system software, syngo CT VA48, supports functionality such as Twin Beam scanning, Fast 3D Align, TrueD 4D Viewer, Fast DE evaluation and improved functionality with extended Field of View. The computer system delivered with the CT scanner is able to run optional post processing applications.
In addition to the previously supported software functionality, which was cleared for the FAST DE Result evaluation of Dual Source and Single Source (dual spiral) data, the subject device will support the FAST DE Result evaluation of data acquired with TwinBeam technology. FAST DE Results evaluation allows to use the optional post-processing features Monoenergetic Plus and Virtual Enhanced.

10. General Safety and Effectiveness Concerns:
The device labeling contains instructions for use and any necessary cautions and warnings to provide for safe and effective use of the device. Risk management is ensured via a hazard analysis, which is used to identify potential hazards. These potential hazards are controlled during development. verification and validation testing. To minimize electrical, mechanical, and radiation hazards. Siemens adheres to recognized and established industry practice and standards.
11. Conclusion as to Substantial Equivalence
SOMATOM Definition AS/AS+ and SOMATOM Definition Edge with FAST DE Results for TwinBeam Data software module has the same intended use and comparable indication for use as the predicate devices. The technological characteristics such as image visualization, operating platform, and image manipulation are same as with the predicate devices. Anv differences in technological characteristics between the subject device and the predicate devices do not raise different questions of safety or effectiveness. The result of all conducted testing was found acceptable to support the claim of substantial equivalence.
The predicate devices were cleared based on non-clinical supportive information including phantom bench test, retrospective review of available patient data, and supportive clinical articles. The results of these tests demonstrate that the predicate devices are adequate for the intended use. The same testing and workflows were used to test the subject device modifications. The comparison of technological characteristics, non-clinical performance data, and software validation 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 SOMATOM Definition AS/AS+ and SOMATOM Definition Edge with FAST DE Results for TwinBeam Data software module testing supports a finding of substantial equivalence.
