Volumendeformation in Echtzeit

(01.01.2001 - 31.12.2002)

As a consequence of the development of efficient volume rendering techniques, growing demand for volumetric deformation models has arisen in the last couple of years. Apart from obvious applications of free-form modeling in visual arts and entertainment, the ability to accurately model local deformation is extremely important in medicinal application such as minimal invasive surgery and computer assisted intervention. In a typical clinical application scenario, tomography data is acquired before the intervention for a detailed surgery planning. During the intervention however the pre-operatively acquired image data does not match the actual situation due to anatomical shifts and tissue resection. In consequence the spacial misalignment must be compensated by adapting the volume data to the non-linear distortion.
