Solid Modelling and Display Techniques for CT and MR Images
Three dimensional solid display of anatomical structure presents information from two-dimensional slice data in a form more closely matched to everyday human perceptual experience, and thus provides detailed information to clinical personnel across a wide range of specialties. Generation of such displays requires segmentation of the slice data acquired from a CT or MR scanner to define the boundaries of the tissue of interest. This step is followed by appropriate solid model display of the bounding surface. Alternative approaches for both segmentation and display are presented with a discussion of performance and computational cost. Examples from a commercially available system in clinical use are included.
