Segmentation Quality Measurement

A 2D phantom is designed to simulate the MRA. This phantom image contains many circles with decreasing diameters such as the cerebrovascular tree shape which is a cone-shaped. Then using the level set segmentation algorithm with this image, we obtain a resultant image containing the vessels. The SA is measured by Eq. 9.48.
