Abstract
Rubber Sheet Masking (RSM) is a fully automated method for reducing motion artefacts in Digital Subtraction Angiography (DSA). RSM is based on Venot's registration method for DSA images but improves this method in two respects. Firstly, local image statistics are better taken into account. Secondly, RSM does not require user interaction to define region of interest for motion registration. Attention has furthermore been paid to fast implementation of the method, and to its clinical usefulness. The conclusion of the study is that RSM compares favourably with the conventional interactive pixel shift methods.© (1989) COPYRIGHT SPIE--The International Society for Optical Engineering.
