Abstract
The registration of image datasets is a common problem in medical
imaging. An example of this is the 2D/3D registration of preoperative
3D CT images and intraoperative 2D X-ray fluoroscopy images. In this
thesis, fast methods of the volume visualisation, especially of the
direct volume rendering, have been investigated on their use for the
calculation of perspective projections for 2D/3D registration. A ray
casting method and a method which takes advantage of a shear-warp
factorisation of the viewing transformation were chosen as suitable and,
hence, implemented. Different kinds of optimisation were applied to the
chosen methods in order to meet the high time requirements for clinical
use.
