Abstract
Abstract An anatomical visualization system includes a first database that includes a plurality of 2-D slice images generated by scanning a structure. The 2-D slice images are stored in a first data format. A second database is also provided that comprises a 3-D computer model of the scanned structure. The 3-D computer model includes a first software object that is defined by a 3-D geometry database. Apparatus are provided for inserting a second software object into the 3-D computer model so as to augment the 3-D computer model. The second software object is defined by a 3-D geometry database, and includes a planar surface. Apparatus for determining the specific 2-D slice image associated with the position of the planar surface of the second software object within the augmented 3-D computer model are provided. Also provided are apparatus for texture mapping the specific 2-D slice image onto the planar surface of the second software object. Display apparatus are provided for displaying an image of the augmented 3-D computer model so as to simultaneously provide a view of the first software object and the specific 2-D slice image texture mapped onto the planar surface of the second software object.
