Corstem CMR Suite

A Fully-Quantitative Autonomous CMR Tool


The Corstem CMR Suite application encompasses two software modules (CorPerfusion  and CorCINE) intended for post-processing of Cardiac MR image series. The application runs on an off-the-shelf computer system and requires minimal user input.

The CorPerfusion module implements a complete, fully automatic pipeline of myocardial perfusion analysis for Cardiac MR imaging. The pipeline integrates automatic motion compensation robust to free-breathing acquisitions, automatic myocardial detection and segmentation, automatic sector delimitation, and automatic perfusion metric computations. CorPerfusion operates on user-specified raw DICOM data files and outputs ventricular and sectorial metrics of perfusion dynamics relevant to clinical diagnosis.

The CorCINE module implements an automatic cardiac diastolic function analysis pipeline on user-specified raw DICOM data files. It tracks clinically relevant cardiac structures over a cardiac cycle to derive displacement and velocity measures. These metrics of cardiac dynamics can be used to assess myocardial health.

The results of the above analyses are displayed on-screen and may be summarized in an automatically generated report.
