research activities at RUBIC

The RUBIC, Research Unit of Biomechanics & Imaging in Cardiology, directed by Dr. Damien Garcia, is affiliated with the LBUM, the department of radiology of the University of Montreal Hospital Center (CHUM) and the imaging & engineering axis of the Research Center of CHUM (CRCHUM). Our research is focused on the analysis of the blood flow in the cardiovascular system (left ventricle, heart valves, coronary arteries, microcirculation…) and the mechanistic evaluation of heart diseases (aortic and mitral stenoses, cardiac dysfunction…) by ultrasound imaging. The main objectives are to develop new clinical non-invasive indices measurable by Doppler echocardiography in order to improve the clinical diagnosis of such diseases. Each project contains three stages:
1) theoretical modeling and/or numerical programming,
2) validation in an in vitro model,
3) in vivo validation and analysis of the clinical applicability in patients.

The RUBIC of CRCHUM is searching for students wishing to make a master or a doctorate in biomedical engineering. The projects' objectives are to analyze the dynamics of the myocardial wall and the 2-D blood flow in the cardiovascular system by Doppler echocardiography. Priority will be given to students with an experience in image processing or numerical analysis. A good knowledge of Matlab is required.

We are also searching for undergraduate students, with a good knowledge of Matlab, for 6-month training periods.
