title: Three-dimensional graphics display of X-ray angiography data.
abstract: A method for making three-dimensional computer graphics displays of in vivo blood vessels is described. Input data are taken from biplane X-ray angiograms using an image-processing system. A display list is built up which is then sent to a high-function graphics system. Real-time interaction is possible using a vector-refresh display where the blood vessel segments are shown as cylinders of the appropriate diameter. Realistic raster representations may be used to give the user insight into the overall topology of the network of vessels. The Winchester Graphics System is described together with explanations of the techniques employed.
