Orthogonal cut view generation for CT scanned data

In clinic practice, a series of transaxial views are usually obtained from a patient in the CAT scanner system. There are interests to present this data at different oblique views. Experience of implementing the generation programs shows the necessity to minimize its processing time in an on line environment. An orthogonal view generation program seems to be the best. This program allows user to specify an orthogonal cut in the displayed view interactively. The processing time for the specified cut is less than four minutes. A second subsequent cut can be drawn in the first generated cut. This orthogonal view generation program permits curvelinear cuts in the displayed view. This curvelinear cut provides a very untradirional dis play in radiology. It is useful in displaying a slice-sectional view of the spinal column of patients. Neuradiologists are interested in using this capability to study the dimension of the spinal column. In this paper, the orthogonal view generation program will be described in detail. The features of this display program will be compared with a number of other alternative programs.
