Abstract

The present invention provides an anatomical visualization and measurement system including a first database of 2-D slice images and a second database including a 3-D computer model defining a first software object. Apparatus is provided for selecting a 2-D slice image from the first database. Apparatus is also provided for inserting a second software object into the 3-D computer model. The second software object includes a planar surface and 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. Apparatus is also provided for texture mapping the 2-D slice image onto the planar surface. Display apparatus is provided for displaying an image which simultaneously provides a view of the first software object and the 2-D slice image texture mapped onto the planar surface. An apparatus and method are also provided for determining structural dimensions and volumes using appropriate scanned 2-D slice image information. The present invention permits an appropriate set of scanned 2-D images to be assembled into a 3-D database, information regarding selected structural features to be segmented out of the 3-D database, and measurements to be made based on these structural features. In addition, the present invention permits a set of oblique images to be generated based on these structural features, which oblique images may themselves be used for measurement purposes.
