Publication number: 20080018645Abstract: The present invention provides an anatomical visualization and measurement system comprising a first database that comprises 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 comprises a first software object that is defined by a 3-D geometry database. Apparatus is provided for selecting a particular 2-D slice image from the first database. Apparatus is also 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 also defined by a 3-D geometry database, and includes a planar surface. The second software object is inserted into the 3-D computer model at the position which corresponds to the position of the selected 2-D slice image relative to the scanned structure.Type: ApplicationFiled: March 23, 2007Publication date: January 24, 2008Inventors: Jeff Dwyer, David Chen, M. Chapman
