Erstellung von 1D und 2D Transferfunktionen für medizinische Anwendungen

Bachelor-Thesis

Direct volume rendering has gained importance as a tool for supporting medical diagnosis based on Computer Tomography and Magnetic Resonance data. 3D visualization tools are nowadays a standard in the clinical environment and have been incorporated in many commercial applications. The standard strategy is based on the mapping of measured data intensities to colors and opacities making use of the so called one dimensional transfer functions.
As a drawbak from this approach, it requires a good degree of expertise in the creation of adequated transfer functions for good quality renderings, which effectively provide useful clinical information.
Further developments in graphics hardware have made possible to introduce transfer functions based on intensity and gradient magnitud for real-time direct volume visualization. The preliminary results are promising. However, the increased complexity introduced by new degrees of freedom in the transfer functions makes this technique less attractive for the clinical application.
The aim of this work is the creation of a development environment for 1D and 2D transfer functions for direct volume rendering, having as main objective its use in the clinical practice.
