Abstract
Magnetic Resonance Imaging (MRI) has become an important technique for imaging cardiovascular diseases.Recent advances in MRI allow fast recording of contrast enhanced myocardial perfusion scans. These MR perfusion scans are made by recording, during a period of 20-40 seconds short axis slices of the heart. The scanning is triggered by the patient's ECG typically resulting in one set of slices per heart beat. For perfusion analysis, the myocardial boundaries must be traced in all images, dividing the heart into the left and right ventricle blood volumes and the myocardium of the left ventricle. Care must be taken not include part of the right or left ventricle blood volumes in the myocardium segment, because this may have a significant effect on the perfusion analysis. On the other hand, for accurate estimation of the perfusion parameters, all of the available myocardium area in the image should be used. In this paper a method is proposed to automatically correct for any inclusion of left and right ventricle into the myocardium segment and optimally place the myocardial boundaries.
