Non-invasive myocardial motion analysis method based on the phase difference magnetic resonance imaging diagnosis of myocardial velocity

摘要

Motion and deformation is assessed and imaged using phase contrast magnetic resonance imaging for determining velocity of a plurality of regions at a plurality of frames during a period of interest such as the cardiac cycle. A region of interest is tracked from frame to frame and based on a known last position and the velocity at the known position. Strain and rotation are determined from the changes in velocity along selected axes.
