Abstract

The Electronic Portal Imaging Device (EPIDs) uses the high energy treatment beam to project the body interior of the patient onto a fluorescent screen that is scanned by a camera. Because of the imaging physics the unprocessed images are very poor in quality. This paper presents an approach that combines an Associative Restoration algorithm with a Fuzzy Image Enhancement technique. By fusion of the electronic portal image with a pre-treatment captured simulator image a higher image quality than by conventional techniques is achieved.
