3D registration and integrated visualization of multimodal clinical data

The authors present here a registration solution and a 3D integrated representation of the fused modalities, CT and SPECT. The registration process is based on the inertial moments determination. The visualization process uses a raycaster philosophy with multiple objects in volume. Functional data is represented with pseudo colour on orthogonal clipping planes, anatomical information is displayed using a raycaster approach with a grey shade look up table. The registration process is evaluated with a phantom derived from a genuine clinical volume. A case study is presented.
