Improving Cardiovascular Risk Assessment with CT Coronary Angiography and Myocardial CT Perfusion
… the further development of CTP techniques. Image noise is a major limitation of current CTP methods. A novel four-dimensional median value filter was developed which selects the most stable voxels over both time and surrounding image space. The technique reduced transient image artifact and …
