3-D imaging and stereotactic radiosurgery

Three-dimensional image processing and analysis applications in stereotactic radiosurgery are discussed. Only simple and rapid methods of 3-D image analysis have been used. However, volumetric image techniques, such as volume rendering and fusion, would give more useful information in treatment planning. The topics dealt with include: treatment space specification; segmentation of structures of interest; model/knowledge-based approach; tumor targeting; beam's eye viewing; dose-volume fusion; isocentric parameter optimization.
