Project Description
PROJECT DESCRIPTION
Miocardia is a solution pack which provides a unique comparative setting of multiple cardiac imaging modalities for the modeling and representation of the Left Ventricle Functionality. Miocardia is meant to be Computer Vision software capable to represent the anatomical and functional structure of a ventricle on 3D. It extracts information from different kind of image modalities of the patient’s heart to build the 3D representation. Deep understanding of myocardial structure of the heart would unravel crucial knowledge for clinical and medical procedures. Although the muscular architecture of the heart has been debated by countless researchers, the controversy is still alive. Diffusion Tensor MRI, DT-MRI, is a unique imaging technique for computational validation of the muscular structure of the heart. By the complex arrangement of my- ocites, existing techniques can not provide comprehensive descriptions of the global muscular architecture. We introduce a multiresolution reconstruction technique based on DT-MRI streamlining for simplified global myocardial model generation. Our reconstructions can restore the most complex myocardial structures and indicate a global helical organization

Left Ventricle Functionality
Most cardiovascular diseases impair the normal motion of the left ventricle (LV). Recent improvements in tomographic imaging devices such as MRI or CT, have led to the creation of 3D computer models that show the dynamics of the LV. Since the mechanical properties of any muscle are determined by the arrangement of their fibres in space, a model that aims to realistically simulate the behavior of this tissue must take into account the spatial distribution of the fibres. In the case of the myocardium it plays a crucial role for the understading of the electromechanical activation sequence in normal and pathologic conditions and the mechanisms of the ventricular resynchronization therapy (pacemaker implantation)
