Paper Abstract

In this paper, we report a new method for the improvement of the perceptual quality in digital angiographic images. This method contains two-steps. In the first step, we process the angiographic image sequence using a new algorithm for the correction of motion artifacts. In the second step, we apply a novel spatially-adaptive temporal filter to the registered image sequence. We demonstrate the improvement of the image quality over the existing methods using actual patient data.
