Background
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.
