Image data set e.g. computed tomography-image data set, visualization method for organ i.e. colon, of patient, involves assigning transparency value to organ tissue, where side of organ facing viewer position is partially transparent

摘要

The method involves defining a virtual viewer position (P) outside an organ tissue (C). Local gradients (G), which specify increase of an absorption behavior between a gas contained in a cavity and the tissue, are determined. A search ray (S) is defined and an angle (Alpha) between the search ray and the gradients is determined. A transparency value is assigned to the tissue in dependence of the angle during visualization. A side of the organ facing the viewer position is partially transparent to enable a view on an inner wall (16) of the side of the organ turned away from the viewer position. An independent claim is also included for a device for visualization of an image data set of an organ.
