A Fast and Stable Method for Detecting and Tracking Medical Organs in MRI Sequences

A discrete dynamic model for defining contours in 2-D medical images is presented. An active contour in this objective is optimized by a dynamic programming algorithm, for which a new constraint that has fast and stable properties is introduced. The internal energy of the model depends on local behavior of the contour while the external energy is derived from image features. The algorithm is able to rapidly detect convex and concave objects even when the image quality is poor.
