Abstract:
1. A method of producing a resultant object data set, which method does not depend on identification and segmentation of overlying bony structures, wherein, a reference object data set is provided, wherein the reference object data set is a matrix of values representing image data which corresponds to physical properties of a three dimensional image subject at different points within the body of the subject, a contrast object data set comprising extrinsic contrast information is provided, the extrinsic contrast information within the contrast object data set is segmented to produce a segmented data set containing only those voxels representing the extrinsic contrast information, the data in the segmented data set is dilated to produce a dilated data set, a mask is created from the dilated data set in such a way that the values of the mask are uniform for all points of the mask which correspond to points in the dilated data set which are represented by the dilated contrast data, and the reference object data set is filtered by the mask to produce the resultant object data set, wherein segmentation of the contrast information to construct a mask with which to filter the reference object data set enables differentiation of physical properties within the body of the subject based upon anatomical position, wherein a three dimensional image of the subject is displayed when all points within the object data set are translated into image voxels within a three dimensional image object data set, and wherein a two dimensional image of the subject may be derived from the three dimensional image object data set.
