Imaging methods and apparatus.

摘要

A method and apparatus for three-dimensional imaging using a plurality of slice images of a specimen (34). A region of interest (36, 38) is selected from within a slice and is extrapolated to subsequent slices. A boundary indicative of a surface of interest is selected from within the region of interest to facilitate generation of an image representative of a three-dimensional surface of interest to be asembled from subsequent slices of the plurality. A viewing surface (68) is defined in relation to a generated surface image which was selected from the boundary. A scaling means assigns a scaled gray level to the three-dimensional image to facilitate three-dimensional viewing of the specimen when it is projected on the viewing surface. Image information is selectably modified by data from the original slice images to add surface density visualization. Means is also provided to facilitate selective segmentation of a three-dimensional image along a plane or planes of interest. An interactive procedure is provided to facilitate cutting of a three-dimensional object from its perspective view (with or without density information).
