cvi42 Software Application

The cvi42 Software Application serves as a medical device for qualified professionals to perform quantitative evaluation and post-processing of cardiovascular MR and CT images. Its scientific foundation lies in integrating digital image processing with machine learning techniques to enable semi-automatic contouring and comprehensive cardiac measurements, thereby supporting diagnostic analysis and clinical decision-making.

The cvi42 Software Application, developed by Circle Cardiovascular Imaging Inc., is designed for qualified medical professionals to view, post-process, and quantitatively evaluate cardiovascular magnetic resonance (MR) and computed tomography (CT) images. This software functions as a medical device, providing digital image processing, visualization, quantification, and reporting tools to support physicians in the evaluation and analysis of cardiovascular imaging studies. It is specifically intended for use with cardiac images acquired from MR or CT scanners.The software offers comprehensive measurement capabilities, including distance, area, volume, mass, signal intensity, Agatston score, and various cardiac function and strain parameters. It integrates machine learning techniques for semi-automatic contouring of regions of interest, with these algorithms trained and tested on anonymized datasets from multiple clinical sites. Performance testing has confirmed the software's compliance with specified design requirements and standards, validating both its traditional and machine learning functionalities, and supporting its safety and effectiveness for its defined use.
