Paper Abstract

We present a method for decomposition of angiographic image sequences into moving layers undergoing translation, rotation, and scaling. We first describe a regularization method for scatter-glare correction which can be used to obtain good estimates of projected x-ray attenuation coefficient. We then compute a set of weighted correlation functions to determine the motion of each layer, and compute the layer densities in the spatial domain by averaging along moving trajectories. We demonstrate the utility of our method by successfully decomposing simulated angiograms into moving layers. We also demonstrate visually acceptable layer decomposition of actual angiograms.
