  • Look Inside

3-dimentional image reconstructed from the data of computer tomography has provided useful infor-mations for the pre-operative evaluation in the field of neurosurgery and plastic surgery. However CT has failed to visualized the 3-dimentional surface image of the central nervous system. On the other hand the progress of high-speed data aquisition technique and 3-dimentional fourier transformation has enabled the practical 3-dimentional image using magnetic resonance imager. However for the visual-ization of a pure surface image of the brain and spinal cord a sophisticated method and special image work station has been necessary. The authors describe a technique for the pure surface image of the brain and spinal cord using a normal mini-com-puter system and magnetic resonance imager. This image has a good corelation to the macroscopic anatomical brain surface (sulci and gyri).
