Three-Dimensional Display of X-Ray CT Image
Multislice images obtained by X-ray CT essentially have a three-dimensional data structure. They are useful for diagnosis and treatment through three-dimensional display.
The surface display of organs is one of the effective methods of three-dimensional display. However, although completely automatic processing of contour extraction is desirable it is very difficult.
For this surface display, it is very important to extract contours of organs.
Accordingly, by using an interactive method, we have developed an algorithm that permits accurate three-dimensional display after extracting images of the cerebral ventricle. Satisfactory results have been obtained.
