Syngo Dynamics (Version VA40F)

syngo Dynamics (Version VA40F) is a comprehensive medical image management and processing software system intended for cardiovascular image review, quantification, and reporting across multiple modalities, operating on a client-server architecture. This version introduces 'Auto EF', an AI/ML-driven science for semi-automated left ventricular ejection fraction calculation from ultrasound images, which was validated through performance testing using clinical data against expert manual measurements to support enhanced cardiac assessment.

syngo Dynamics (Version VA40F) is a software-only medical image management and processing system (MIMPS) designed for trained healthcare professionals to review, edit, manipulate image data, and generate quantitative data, qualitative data, and diagnostic reports. It supports various imaging modalities, primarily focusing on cardiac applications like echocardiography, angiography, CT, and MR for adult and pediatric medicine, as well as vascular ultrasound and Ob/Gyn ultrasound (fetal echocardiography). The system operates on a client-server architecture, deployable as a standalone device, an integrated module within EHR systems, or a Multi-Modality Cardiovascular (MMCV) setup. It provides tools for image viewing, reporting, and processing, with multiple access strategies including a Workplace, Remote Workplace, and a browser-based WebViewer, now supplemented with a 'Portal' access option. A significant update in Version VA40F is the 'Auto EF' feature, an AI/ML-based algorithm for optional semi-automated calculation of left ventricular ejection fraction (LVEF) from ultrasound images, complementing existing manual methods. This user-controlled tool, with manual override capabilities, was validated using clinical data from 150 diverse cases, comparing its output to a ground truth established by experienced sonographers using the Modified Simpson's Rule. The Auto EF achieved a Pearson’s correlation coefficient of 0.827 (P<0.0001) against the ground truth, meeting predefined acceptance criteria. The system continues to offer various image processing algorithms, quantitative tools, and supports DICOM and HL7 communication protocols, with an emphasis on cybersecurity and adherence to recognized industry standards.
