The Corstem CMRsuite application encompasses two software modules (CorPerfusion  and CorVentricle) 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 for fully quantitative pixelwise 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 raw DICOM data files and outputs per-pixel and sectorial metrics of perfusion dynamics in absolute physical metrics relevant to clinical diagnosis.

The CorVentricle module implements an automatic ventricular function analysis pipeline on user-specified raw DICOM data files. Following an automatic segmentation of the left and right ventricles, cardiac structures are tracked over a cardiac cycle to derive displacement, velocity, and volumetric measures. These clinically relevant metrics can be used to assess cardiac health.

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