1. A method of evaluating data associated with direct volume renderings, comprising:
- automatically electronically analyzing a plurality of local histograms derived from a volume rendering data set; and
programmatically generating data that is used for at least one of (a) material classification or (b) material detection, of materials in the data set, including materials of similar intensity, based on the analyzing step.

Abstract
Methods and apparatus are configured to provide data to render (medical) images using direct volume rendering by electronically analyzing a medical volume data set associated with a patient that is automatically electronically divided into a plurality of local histograms having intensity value ranges associated therewith and programmatically generating data used for at least one of tissue detection or tissue classification of tissue having overlapping intensity values.

36. A method for providing a tissue exploration tool to allow a physician to interactively analyze medical volume data sets in a visualization system, comprising:
-
allowing a user to electronically select a partial range of interest in an intensity scale of voxel data to thereby allow the user to interactively investigate voxels in a volume rendering data set;
electronically generating a partial range histogram associated with the selected partial range; and
electronically fitting an adaptive trapezoid to the partial range histogram to render an image of material associated with the selected partial range. - View Dependent Claims (37)

38. A method for visualizing images of volume data sets, comprising:
-
iteratively electronically subdividing a respective volume data set using local histograms of neighborhood voxel data to allocate the neighborhoods of data into partial range histograms, each partial range histogram having voxels with intensity values in a defined range; and
electronically automatically identifying different materials in the volume data set, including materials having overlapping image intensity values which may be distributed over a target volume of interest. - View Dependent Claims (39)
