Intended Use
syngo.CT Extended Functionality is intended to provide advanced visualization tools to prepare and process medical images for diagnostic purpose. The software package is designed to support technicians and physicians in qualitative and quantitative measurements and in the analysis of clinical data that was acquired and reconstructed by Computed Tomography (CT) scanners, and possibly other medical imaging modalities (e.g. MR scanners). An interface shall enable the connection between the syngo.CT Extended Functionality software package and the interconnected CT Scanner system. Result images created with the syngo.CT Extended Functionality software package can be used to assist trained technicians or physicians in diagnosis.
Device Story
syngo.CT Extended Functionality is a software bundle providing advanced visualization and measurement tools for medical images (CT/MR). It functions as a post-processing application for clinical data acquired by imaging scanners. The device includes specific extensions for Interactive Spectral Imaging, vascular assessment, oncology (nodule evaluation), bone mineral density (Osteo), neuro DSA, dual energy ROI, endoscopic views, and HU thresholding. It is operated by technicians or physicians in a clinical setting. The software processes image data to generate visualizations and measurements, which are then reviewed by clinicians to assist in diagnosis. The device supports multiphase data grouping and editing of pre-generated results. It does not acquire images directly but connects to imaging systems via an interface.
Clinical Evidence
Bench testing only. Performance was validated through phantom-based testing for the Interactive Spectral Imaging feature and verification of software modifications. No clinical data was required or provided. Testing confirmed that the device performs as intended and meets safety/performance standards including DICOM (PS 3.1-3.20), IEC 62304, ISO 14971, and IEC 62366-1.
Technological Characteristics
Software-based post-processing application (SOMARIS/8 VB40). Operates on CT/MR image data. Features include spectral imaging, vascular/oncology/osteo/neuro/dual-energy/endoscopic tools. Connectivity via DICOM. Complies with IEC 62304 (software lifecycle), ISO 14971 (risk management), and IEC 62366-1 (usability).
Indications for Use
Indicated for use by trained technicians and physicians to provide advanced visualization, qualitative and quantitative measurements, and analysis of medical images (CT and MR) for diagnostic purposes.
Regulatory Classification
Identification

Tests for the Plugin "Interactive Spectral Imaging"" has been conducted to show that the feature ISI operates as intended.
Non-clinical tests and a phantom-based bench test have been conducted to establish the proficiency of the 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.
# VIII. Conclusions
syngo.CT Extended Functionality has the same indication for use as the primary predicate device. The technological characteristics such as image visualization, operating platform, and image measurement are the same as the predicate devices. For the subject device, syngo.CT Extended Functionality, Siemens used the same testing with the same workflows as used to clear the primary predicate device. Siemens considers syngo.CT Extended Functionality to be as safe, as effective, and with performance substantially equivalent to the commercially available predicate devices.
