Intended Use

Syngo.CT Single Source Dual Energy is designed to operate with CT images which have been acquired with Siemens Dual Spiral Single Source scanners. The various materials of an anatomical region of interest have different attenuation coefficients, which depend on the used energy. These differences provide information on the chemical composition of the scanned body materials. syngo.CT Single Source Dual Energy combines images acquired with low and high energy spectra to visualize this information. Depending on the region of interest, contrast agents may be used.

Device Story

Post-processing software package for CT images acquired via Siemens Dual Spiral Single Source scanners. Transforms high and low energy spectral data into material-specific visualizations; utilizes energy-dependent attenuation coefficients to characterize tissue/materials. Operates on syngo.via client-server platform. Used by radiologists in clinical settings to assist in diagnostic tasks like kidney stone composition, liver fat mapping, and bone marrow analysis. Output consists of processed images and quantitative data (e.g., Rho/Z values, fat maps) displayed on workstation. Assists clinicians in material differentiation and tissue characterization; supports diagnostic decision-making. Benefits include improved visualization of energy-dependent materials compared to single-energy CT.

Clinical Evidence

No prospective clinical trials. Evidence consists of phantom bench testing and retrospective analysis of patient data to validate Rho/Z and Liver VNC fat map features. Supportive literature provided to demonstrate usability and performance of new application classes. Software verification and validation testing confirmed specifications met acceptance criteria.

Technological Characteristics

Post-processing software package; operates on syngo.via client-server platform. Features include Rho/Z (electron density/effective atomic number) and Liver VNC (fat map). Conforms to DICOM (PS 3.1-3.20), IEC 62304 (software lifecycle), ISO 14971 (risk management), IEC 60601-1-6 (usability), and IEC 60601-1-4 (programmable electrical medical systems).

Indications for Use

Indicated for use with CT images from Siemens Dual Spiral Single Source scanners to visualize chemical composition of body materials. Applications include Monoenergetic, Monoenergetic Plus, Brain Hemorrhage, Liver VNC (including fat content visualization), Gout Evaluation, Bone Marrow, Rho/Z (electron density/effective atomic number), and Kidney Stones (differentiation of uric acid vs. non-uric acid). Kidney Stones application is for support; final diagnosis requires clinical history and urine testing by a radiologist. Accuracy is decreased in obese patients.

Regulatory Classification

Non clinical tests (integration and functional) were conducted for syngo.CT Single Source Dual Energy during product development. The modifications described in this Premarket Notification were supported with verification/validation testing. The risk analysis was completed and risk control implemented to mitigate identified hazards. The testing results support that all the software specifications have met the acceptance criteria. Testing for verification and validation of the device was found acceptable to support the claims of substantial equivalence. # 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. {8}------------------------------------------------ ### 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.
