Abstract
A sequential analysis method for angiograms is implemented and explained. A multi-resolution technique is used to segment the subtracted angiogram. The system is an improved version of our earlier work. A two step process for flow computation and interpretation is explained. First a bi-directional segmentation is applied to the image followed by the computation of the peak arrival time associated with the indicator dilution. Methods are suggested to infer flow information and quantified stenosis from integration of the peak arrival time map with densitometric information.
