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.
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.
