Research Activities:
Tomographic reconstruction and the display of the reconstructed object
for medical diagnostics, therapy planning, and simulated surgery are at
the core of my Ph.D. dissertation research currently underway.
-
3D reconstruction: Presently I'm working on the development of fast and
accurate, both sequential and parallel, algorithms for tomographic 3D
reconstruction from sparse sets of projection images, acquired by means
of X-ray, PET, or SPECT.
-
Computer graphics and image processing, in particular its use for
visualization in medicine. I have recently developed a ray-driven
approach for splatting which greatly facilitates splatting for
perspective viewing.

A tomographic reconstruction of the Shepp-Logan phantom using an
iterative ART-type algorithm. (Reconstruction grid size was 128x128
voxels, 80 projection images were used, and the computation time was
40s on a standard SGI Indigo workstation).
|
The next algorithm unifies raycasting principles with the mechanisms of
splatting to yield a ray-driven splatting approach. Unlike original
voxel-driven splatting, the new approach runs at the same
speed for perspective viewing than for orthographic projection. (Click on the
