Temporomandibular disk segmentation using fast level set method

Original language description

Our task is to segment a temporomandibular (TM) disk from MRI images of a human head during jaw opening and closure. It is a relatively difficult problem because the TM disk movement is very complicated and its shape changes significantly during the motion. The segmentation results can be used for clinical diagnostics and further modeling using the finite element method. We have selected a novel fast discrete level set method because of its hight computational efficiency due to discrete contours representation by two sets of points, corresponding to the inner and outer edge of object boundary, while preserving all advantages of traditional level set techniques. This technical report describes our first approach to the TM disk segmentation and is aimedat the proposed method segmentation ability and results evaluation. We have explained problems we have met and offered some solutions. At the end of the report, we describe the proposed improvements for the enhacements of the segmentation
