Mirrored LH Histograms for Cardiac Vessel Analysis and Visualization

Studien-/Diplomarbeit

The quality of direct volume renderings is strongly influenced by the transfer function applied. The purpose of the transfer function is to highlight aspects of the volume data that are of interest to the user. In medical image visualization usually object boundaries are of special interest, since they reveal shapes of organs or vessels and their spatial relations. Regarding Cardiac Multi-Slice CT (MSCT) data, vessel analyisis and visualization is of special importance in order to assist the clinician in the diagnosis of the so called coronary artery disease.
Just recently, Mirrored LH Histograms[[1] http://w3.bmt.tue.nl/en/research/divisions_bme/biomedical_imaging_modeling/biomedical_image_analysis/research/multivalued_image_analysis_visualization/transfer_functions/mirrored_lh/ ]have been proposed as a new transfer function domain for material boundary visualization in direct volume renderings.

In this thesis, the quality of mirrored LH space for cardiac CT data visualization and analysis shall be examined. Hence, a volume renderer employing a transfer function based on mirrored LH space has to be implemented.
Furthermore, possibilities to exploit mirrored LH histograms in order to detect vessel boundaries and analyze vessel properties should be researched.
