An approach to location of a region including the posterior and anterior cruciate ligament in the MR knee images has been developed. The proposed method of the PCL location in T1-weighted MR knee images is based on entropy (or energy) measure of fuzziness and fuzzy C-means (FCM) algorithm. Then, edges of a region of interest containing the ligament are found. The procedure has been tested on clinical T1- and T2- weighted MR knee images resulting in a 3D visualisation.
