Medical imaging and computational fluid dynamics (CFD) modeling have been combined to obtain detailed knowledge of local hemodynamics, known to play an important role in cardiovascular diseases. Given the absence of a "gold standard" to measure the blood velocities in vivo, simulation of X-ray angiograms was proposed as a method to indirectly validate the accuracy of image-based CFD analysis...
For a proper diagnosis and post treatment evaluation of acute myocardial infarction, angiographic measures of the myocardial perfusion such as the myocardial blush grade are pivotal. The presence of blood with contrast agent in heart tissue can be observed as a darkening of the target region. Currently, the myocardial blush grade is established by a visual analysis of this darkening. We present methods...
