This article deals with a segmentation of MR images in temporomandibular joint (TMJ) area. The TMJ belongs to small but the most overloaded joint of the human body. It consists of the head of the mandible and articular fossa [1]. Between them is the mandibular disc. The mandibular disc is a cartilage for a force transmission. The physiological placement of the disc is on the top of the mandibular head. One of the frequent diseases is the disc dislocation from the physiological placement therefore there is a blocking of the mandibular head movement. In the worse case it can come to the total disc deformation [2]. The aim of this work is to obtain the most exact image or model of the mandibular disc for the right assesment of a treatment in order to minimize the invasive surgery. There was chosen an active contour method based on level set partial differential equation for the mandibular disc extraction. There was found the boundary of the mandibular disc in the noised image of low contrast with suitable parameters and initial curve without of any kind of preprocessing. The head of the mandible was extracted by regionbased four-phase level set segmentation method. The article shows our results of the segmentation of some MR slices with visible mandibular disc and head. These results are poised to following postprocessing which will be the 3D model of the mandibular disc creation.
