Abstract
The best assessment of temporomandibular joint (TMJ) can only be done by the scanning the jaw and getting an image without invivo analysis which causes patient discomfort. There have been innumerable efforts to get the best view using CT techniques for three dimensional visualisation. But very few have done work using MRI techniques.
The TMJ is an integral part of the jaw and helps in mastication and biting. Since the joint is a hinge sliding articulation any dislocation causes immense pain and discomfort.
To get a better assessment of the TMJ, MRI techniques have been used for data acquisition. The principle technique of MRI imaging has been done with spin echo method for better tissue specificity.
The proposed work was done using computer graphics and image processing techniques to give better estimates of the volume of the TMJ by creating three dimensional reconstructions of the surface and then computing the volume of the reconstruction. Gray level images of the sections were input to an interactive graphics, ICON that reconstructed the surface, computed the volumes and also computed rotations of the volume so that the TMJ can be viewed in three dimensions.
The work was carried utilizing the visualisation facility available in the University of Medicine and Dentistry of New Jersey. These facilities include Hewlett Packard series 9000 solids rendering technical workstations and 3D reconstruction and visualisation software developed under a joint collaboration between the Laboratory of signals and image processing of the INSERM group of the University of Rennes, in France and the academic computing centre of the UMDNJ.
