Abstract
An apparatus for determining a disease parameter describing a type of cardiac disease includes a unit for reading input parameters representing 3D myocardial velocity fields with voxel wise 3D velocity information. The velocity vectors represent velocity of a voxel of a region of the heart at a predefined time point or time interval; a velocity vector depicts a voxel wise 3D velocity of the myocardium with different magnitude. A processor applies an algorithm to obtain a rotation parameter and/or strain-rate-tensor representing local curl of the input parameters and local rate of strain at a certain spatial point, at a certain time point or time interval. A processor calculates the disease parameter on the basis of the rotation parameter and strain-rate-tensor, dividing an absolute value of the rotation parameter by an eigenvalue. The disease parameter reflects a proportion to overall deformation of local layer shearing with regard to local pure deformation.
