3D-biomedical modeling: merging image processing and computer aided design

A computerized system is described for 3-D reconstruction, manipulation, geometrical analysis, and postprocessing of biomedical models. This system, based on an IRIS 3020 graphics workstation from Silicon Graphics, can perform (1) preprocessing of 3-D biomedical data coming from serial slices, (2) 3-D generation and coding of the underlying structures, and (3) display, interactive object manipulation, and geometrical analysis. The main features of the modeler are the availability of modular built-in functions and the flexibility of adding dedicated or general-purpose functions. Such functions can range from specific image preprocessing algorithms (soft tissue segmentation, edge and contrast enhancement, contour detection) to postprocessing functions that allow visualization of modeling analysis results.<>
