Intended Use

syngo.CT Single Source Dual Energy is designed to operate with CT images which have been acquired with Siemens Twin Beam 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 Twin Beam Single Source scanners. Inputs: two reconstructed image datasets with different X-ray spectra. Processing: motion correction algorithm; linear blending of datasets; material decomposition based on energy-dependent attenuation coefficients. Outputs: color-coded overlays, multiplanar reformations (MPR), and quantitative visualizations (e.g., iodine uptake, uric acid differentiation). Used in clinical settings by radiologists to assist in diagnosis of conditions like gout, kidney stones, and lung parenchyma analysis. Software operates on syngo.via client/server platform. Enhances clinical decision-making by providing material-specific information not visible in standard single-energy CT. Benefits include improved tissue characterization and potential reduction in need for additional diagnostic procedures.

Clinical Evidence

Bench testing and retrospective clinical validation. Phantom testing validated Rho/Z and Kidney Stones applications. Retrospective studies validated Gout Evaluation, Lung Analysis, Monoenergetic Plus, Bone Removal, Liver VNC, and Hard Plaques.

Device Description Dual energy offers functions for qualitative and quantitative evaluations. Dual energy CT can be used to improve the visualization of the chemical composition of various materials in the human body when compared to single energy CT. Depending on the organ of interest, the user can select and modify different application classes or parameters and algorithms. syngo.CT Single Source Dual Energy (twin beam) Software Package is a post processing application package consisting of several post-processing application classes that can be used to improve visualization of various energy dependent materials in the human body. This software application is designed to operate on the most recent version syngo.via client/server platform, which supports preprocessing and loading of datasets by syngo.via depending on configurable rules. After loading the two reconstructed image datasets acquired with two different X-ray spectra into syngo.CT Single Source Dual Energy (twin beam), a correction algorithm is used in order to minimize motion effects. They are then displayed using linear blending with selectable mixing ratio and color scale. Multiplanar reformations (MPR) of the volume are shown in 3 image segments, which are initialized as sagittal, coronal and axial view. After arriving at an initial diagnosis on the basis of the CT-images, the user can choose one of the following application classes: - . Monoenergetic - Bone Removal ● - Liver VNC - Lung Analysis - Gout Evaluation ● - Monoenergetic Plus ● - Virtual Unenhanced . - Rho/Z ● - Hard Plaques . - Kidney Stones . These application classes are designed for specific clinical tasks, so that algorithms, additional tool buttons, the use of colored overlay images and image representation (for example MPR or maximum intensity projection) is optimized correspondingly. A listing of major device modifications within the scope of the new software version SOMARIS 8/VB20 is as follows: - . The Use of Twin Beam Images for additional Dual Energy post-processing Applications (Lung Analysis and Gout) - Modified Indications for Use Statement ● An additional modification is the support of Offline Ranges for Dual Energy which allows the user to select the required post-processing for reconstructed Dual Energy image series at the scanner. {5}------------------------------------------------ ## V.

Performance Data ## Software Verification and Validation Testing 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. ### Non-Clinical / Clinical Testing Summary syngo.CT Single Source Dual Energy (twin beam) is designed to fulfill the requirements of the following safety and performance standards: | Recognition Number | Product Area | Title of Standard | Publication Date | Standards Development Organization | |-----------------------|-----------------|-------------------------------------------------------------------------------------|---------------------|------------------------------------------| | 12-300 | Radiology | Digital Imaging and Communications in Medicine (DICOM) Set; PS 3.1 – 3.20 | 06/27/2016 | NEMA | | 13-32 | Software | Medical Device Software –Software Life Cycle Processes; 62304:2006 (1st Edition) | 08/20/2012 | AAMI, ANSI, IEC | {7}------------------------------------------------ | Recognition Number | Product Area | Title of Standard | Publication Date | Standards Development Organization | |-----------------------|--------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------|------------------------------------------| | 5-40 | Software/ Informatics | Medical devices – Application of risk management to medical devices; 14971 Second Edition 2007-03-01 | 08/20/2012 | ISO | | 5-95 | General I (QS/RM) | Medical devices - Part 1: Application of usability engineering to medical devices IEC 62366-1:2015 | 06/27/2016 | IEC | | 19-4 | General II (ES/EMC) | AAMI / ANSI ES60601-1:2005/(R)2012 and A1:2012, Medical electrical equipment - part 1: general requirements for basic safety and essential performance (IEC 60601-1:2005, mod) | 07/09/2014 | AAMI, ANSI | Performance tests were conducted to test the functionality of the syngo.CT Single Source Dual Energy (twin beam) post-processing application. A clinical validation has been conducted to show that both application classes "Gout" and "Lung Analysis" operate as intended. We have shown that this software application based on Twin Beam Dual Energy data successfully visualizes urate depositions as a consequence of gout. The second validation shows that the application class Lung Analysis for Twin Beam data successfully calculates Lung PBV and Lung Vessels images from contrast enhanced Dual Energy CT-scans of the lung. Both application classes do not offer additional or new application features compared to the secondary predicate device. Furthermore, phantom bench testing and clinical validation in a retrospective study was conducted to test the functionality of the remaining application classes Rho/Z and Kidney Stones. Retrospective clinically validated studies were conducted to test the performance for applications classes Monoenergetic Plus, Bone Removal, Liver VNC, and Hard Plaques, as well as the predicate device application classes. These studies demonstrate that the subject device using twin beam datasets performs as well as the predicate device applications that were tested using the same methods. Supportive articles that demonstrate the usability of the application classes 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. ## 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, and radiation hazards, Siemens adheres to recognized and established industry practice and standards. # VIII. Conclusions syngo.CT Single Source Dual Energy (twin beam) has the same intended use and similar indication for use as the predicate devices. The technological characteristics such as image visualization, operating platform, and image manipulation are the same as the predicate devices. The result of all testing conducted was found acceptable to support the claim of substantial equivalence. The predicate devices were cleared based on non-clinical supportive information and clinical images. The results of these tests demonstrate that the predicate devices are adequate for the intended use. 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. For the subject device, syngo.CT Single Source Dual Energy (twin beam), Siemens used the same testing with the same workflows as used to clear the primary predicate device. Since both devices were tested using the same methods, Siemens believes that the data generated from the syngo.CT Single Source Dual Energy (twin beam) testing supports a finding of substantial equivalence.
