The study and analysis of blood vessel geometry hasbecome the basis of medical applications related to earlydiagnosis and effective monitoring of therapies in vasculardiseases. This paper presents a new method to trace the outline ofblood vessels from imperfect images and extract usefulinformation about their dimensions in an automated manner.The system consists of a segmentation procedure that uses twoActive Contours to detect blood vessel boundaries and a novelapproach to measure blood vessel diameters directly as thedistance between two points. We have succeeded in designing andimplementing an automated, robust, measurement method that isnot only accurate (it takes away human error) but also user-friendly and requires very little image pre-processing. Thesystem is tested with a set of grey scale images of blood vessels.Results of all the aspects of the design and implementation arepresented along with graphs and images.Keywords- blood vessel diameter; snake; Active Contours;measurement system
