Algebraic discrete tomography
Tomography concerns the reconstruction of patterns from images taken from various angles. It is widely 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 if it 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, linear algebra and number theory. Besides some practical results will be shown.
