Cardiac CT Function Software Application
Overview
The Cardiac CT Function Software Application by Circle Cardiovascular Imaging is an advanced software tool designed to assist medical professionals in analyzing cardiac function from multi-phase, multi-slice cardiovascular CT angiography images. It leverages AI/ML algorithms to accurately segment cardiac structures, including the left and right ventricles, and compute key function metrics such as end diastolic volume (EDV), end systolic volume (ESV), stroke volume (SV), ejection fraction (EF), cardiac output (CO), cardiac index (CI), and LV myocardial mass.
This application is part of Circle’s broader cvi42 platform, which offers a comprehensive, vendor-neutral solution for cardiovascular imaging analysis across both CT and MR modalities. The software provides both manual and semi-automatic segmentation capabilities, along with 2D/3D visualization and multiplanar reconstruction of original CT data. It aims to improve patient throughput, accuracy, and reproducibility in cardiac imaging workflows, supporting faster, more reproducible, and efficient interpretation of studies.
The cvi42 platform, including the Cardiac CT Function module, integrates seamlessly with existing systems and workflows, offering full DICOM and PACS connectivity. It is utilized globally in over 1700 hospitals across more than 90 countries, demonstrating its widespread adoption and clinical validation.
