Salix Central

Salix Central is a Class II web-based medical image management and processing system designed as an adjunctive tool for the qualitative and quantitative assessment of cardiac CT images, specifically for coronary plaque, stenosis, and calcium scoring. Utilizing a SaaS model hosted on AWS, the device employs machine learning-enabled outputs and interactive post-processing tools, demonstrating substantial equivalence and successful performance testing.

A determination has been made regarding the Salix Central device, confirming its substantial equivalence to legally marketed medical devices. This Class II device, identified as a medical image management and processing system, is designed for viewing, post-processing, and analyzing cardiac computed tomography (CT) images acquired in a DICOM Standard format. It provides tools for the qualitative and quantitative assessment of physician-identified coronary plaques and stenosis in coronary computed tomography angiography (CCTA), as well as for performing calcium scoring in non-contrast cardiac CT. Intended to complement standard care, Salix Central serves as an adjunctive tool for qualified medical professionals experienced in cardiac CT image examination. The Salix Central device is a web-based software application delivered via a SaaS model and hosted on AWS cloud services. It offers interactive post-processing tools for trained radiologists and cardiologists to analyze cardiac CT image data, aiding in the preparation of standard coronary reports. The device's substantial equivalence was established through a comparison to a predicate device, the cvi42 Auto Imaging Software Application, highlighting similarities in intended use, features, and performance. Comprehensive performance testing, including verification and validation, was conducted on the device's machine learning-enabled outputs for calcium scoring, centerline extraction, vessel labeling, and lumen/vessel wall segmentation, demonstrating that it exceeded all pre-defined acceptance criteria.
