GNCG-SPECT Reconstruction
This page features some short image sequences
related to my
dissertation:
Simultaneous Activity and Attenuation Reconstruction
in Single Photon Emission Computed Tomography,
a Nonlinear Ill-Posed Problem.
All figures in the printed version
may be found under this link.
A summary of my thesis (in German) my be found here.
This page is still under developement.
The movie sequences are in animated GIF format, they are best viewed using netscape (2.0 or later) on a computer with true color graphics. Image quality on a standard 256 color display may be very poor.
