Extraction of Bood vessels in X-Ray Angiography Image using Fuzzy Logic

The accurate and automated analysis of vessel is a valuable tool in medical imaging since it is applicable to many medical applicationsinvolving diagnosis of atherosclerosis, surgical or treatment planning, monitoring disease progress or remission, and comparing efficacies oftreatment. In this paper an automatic vessel edge detection algorithm is proposed based on Fuzzy logic. Our proposed method follows the stepsfirstly pre processing step to remove varying background, which is the combination of wiener filtering and morphological operators andsecondly detection of vessel edges by fuzzy inference system. Experiments on Angiograms show promising detection results
