Method and apparatus for visualizing a limited part of a 3D medical image-point-related data set, through basing a rendered image on an intermediate region between first and second clipping planes, and including spectroscopic viewing of such region
First Claim
1. A method for visualizing a limited part of a 3D medical image-point-related data set, said method being based on selectively suppressing a geometrically selected part of the data set and rendering an image based on any non-suppressed part of the data set,said method being characterized in that said selected part comprises a first selection containing all points associated to a nearer region with respect to a first clipping plane and moreover all points associated to a farther region with respect to a second clipping plane, respectively, thereby making the rendered image being based on an intermediate region between said first clipping plane and said second clipping plane, wherein said first clipping plane and said second clipping plane cooperate to form a stereoscopic plane couple that when differentially shifted to other positions maintains the orientations of associated pseudo-planes, and that when superposing point information pertaining to various stereo couple a three-dimensional stereo image of a region covered by such shifted stereo couples is derivable.

Abstract
For visualizing a limited part of a 3D medical image-point-related data set, Selectively, a geometrically selected part of the data set is suppressed and an image rendered based on any non-suppressed part of the data set. The selected geometrically selected part includes a first selection containing all points associated to a nearer region with respect to a first clipping plane, and all points associated to a farther region with respect to a second clipping plane, respectively. The image rendered thereby is based on an intermediate region between the first clipping plane and the second clipping plane.
