A computer system and a method to segment two dimensional Magnetic Resonance Images that include a substructure is disclosed herein. The method consists of first receiving a set of MRI. The segmentation is then performed by the user on the first image of the set. Using this information, the system proceeds with the segmentation of the other images in the set, by first, estimating the center position of the substructure. The system then find the pixel of the substructure's contour for different angular positions about the center of the substructure. This is achieved by the system by predicting the contour position and using that predicted position to find the position of the pixel belonging to the contour that corresponds to the current angular position. Having connected the pixels of the contour, the system fills the substructure.
