More Information

No
The document describes post-processing software for CT images that uses dual-energy techniques to differentiate materials based on their attenuation properties. There is no mention of AI, ML, or related concepts like deep learning or neural networks in the intended use, device description, or performance studies sections. The functionality described is based on established physics principles of dual-energy CT.

No
The device is a post-processing software package that aids in visualizing medical images for diagnostic purposes, rather than directly treating or preventing disease.

Yes.

The device is a post-processing application that analyzes CT images to provide information on the chemical composition of scanned body materials, differentiate specific conditions (e.g., uric acid kidney stones), and aid radiologists in making a final diagnosis. This directly supports the diagnostic process.

Yes

The device is described as a "Software Package" and a "post processing application package" that operates on a client-server platform. While it processes images from a CT scanner, the device itself is presented as software for post-processing and visualization, without mention of accompanying hardware components being part of the submitted device.

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

Here's why:

  • IVDs are used to examine specimens derived from the human body. The description of syngo.CT Single Source Dual Energy clearly states it operates on CT images acquired from a scanner. It processes and visualizes information from these images, which are representations of the internal structure of the body, not biological specimens like blood, urine, or tissue.
  • The intended use is for post-processing and visualization of CT images. The device helps radiologists interpret the images by highlighting different materials based on their energy attenuation properties. While this information can be used to support a diagnosis, it is not a test performed on a biological sample.
  • The device description focuses on software for image processing and visualization. It details application classes for analyzing CT data, not for analyzing biological samples.

Therefore, syngo.CT Single Source Dual Energy is a medical device, specifically a radiological image processing software, but it does not fit the definition of an In Vitro Diagnostic.

Non-Clinical Testing Summary

Performance tests were conducted to test the functionality of the syngo.CT Single Source Dual Energy. Phantom bench testing and retrospective analysis of available patient data was conducted for application classes Rho/Z and feature Fat Map. Supportive articles that demonstrate the usability of application class Rho/Z and feature Fat Map for Liver VNC were provided to support device performance and functionality.

These tests have been performed to test the ability of the included features of the subject device. The results of these tests demonstrate that the subject device performs as intended. The result of all conducted testing was found acceptable to support the claim of substantial equivalence.

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

syngo.CT Single Source Dual Energy 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 similar to the predicate devices. Any 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 syngo.CT Single Source Dual Energy testing supports a finding of substantial equivalence.
