Outline of Final Research Achievements

Magnetic resonance imaging is one of popular imaging system showing lesions and anatomical structures in body as well as Computer Tomography, but MR is not good for showing the hard tissue. To clarify the usage of MR data as 3D morphological assessment of bone, we developed the procedure of generating 3D images of facial skull from multiple sliced MR images and we studied the reliability of this image by classical cephalometric analysis procedure. Our result well showed the precise of anatomical reference point on the facial skull and also showed the possibility of clinical application of 3D images of tissues generated from MR images
