Contiguous transaxial high resolution CT scans of more than 100 patients with craniofacial deformities and orthopedic disorders were obtained. The CT scan examinations were used diagnostically in determining the need for surgery and for planning therapy. The serial section data was reconstructed in a three-dimensional form with surface and transparent volumetric computer graphics processing techniques. Real time sequences showing the presence of internal abnormalities in these patients were produced and recorded on video tape. This study demonstrates the feasibility and technical requirements of three-dimensional volumetric visualization for diagnostic evaluation of patients with craniofacial and orthopedic disorders.
