Corstem is a Montreal-based artificial intelligence medical imaging software developer. Our AI-powered tools are currently setting the standard in automatic dynamic cardiac image analysis by replacing multiple legacy imaging modalities into a single exam, namely, Cardiac MR. We enable a whole new level of efficiency and automation for cardiac diagnostic aid to save valuable physician and patient time. Our tools have been developed, validated, and implemented in partnership with the National Institutes of Health (NIH) in the US as well as major hospital centers in Canada.

AUTOMATIC MOTION COMPENSATION
“significantly improve frame-to-frame appearance consistency”
CorMoCo is an automatic universal medical image processing application intended to compensate both rigid and non-rigid motion in cardiac magnetic resonance (CMR) image series. Typical motion compensated by CorMoCo includes, but is not limited to, respiration, heart beating, guttural muscle contractions, patient movement, diaphragm vibration, and neighboring organ deformations. CorMoCo is also designed to preserve voxel intensity fluctuations found in perfusion or contrast-enhanced image series. The machine processes a typical CMR image series under 10 seconds.
The CMR Suite encompasses two cardiac magnetic resonance imaging processing and analysis modules: CorPerfusion and CorCine.
FULLY-QUANTITATIVE myocardial perfusion:
CorPerfusion is an automatic medical image processing application intended to extract clinically-relevant quantitative metrics in cardiac magnetic resonance (CMR) perfusion image series. It fully automates image processing for the quantification of myocardial blood flow (MBF) pixel maps from first-pass contrast-enhanced cardiac magnetic resonance perfusion images. The system removes the need for laborious manual quantitative CMR perfusion pixel map processing and can process prospective and retrospective studies acquired from various imaging protocols.
CorCine is an automatic medical image processing software tool intended to extract clinically-relevant functional metrics in CINE magnetic resonance imaging (CINE-MRI) image series. It is a highly efficient and precise automatic tracking technique that is generalizable to clinically-relevant cardiac structures. CorCine automatically computes LV ejection fraction, myocardial strain, and tricuspid annular plane systolic excursion (TAPSE)
The CMR Suite application implements:
Fully automatic myocardial perfusion analysis for cardiac magnetic resonance imaging (CorPerfusion). The software processes designated raw DICOM data files and outputs the ventricular and sectorial metrics (myocardial blood flow maps) of perfusion dynamics relevant to clinical diagnosis.
An automatic cardiac anatomy tracking module (CorCINE). The software processes designated raw DICOM data files and outputs the motion metrics such as displacement and velocity relevant to clinical diagnosis.
