Title:
An introduction to discrete tomography

Abstract of Talk

Tomography concerns the reconstruction of patterns from images taken
from various angles. It is applied in scans where often 720 or 1024
images of an object are made. The method is based on Fourier analysis.
It cannot be used if the material is changing quickly or is damaged by
making pictures. Discrete tomography is a recent development where the
object consists of only few materials and the number of pictures is
well under 40. The underlying theory is quite different. In the
lecture some basic techniques are explained, from discrete mathematics
and number theory. Besides some practical results will be shown.
