Tomography and inverse scattering
Roman Novikov Ecole Polytechnique
Tomography is known first of all as a research domain related with the problem of determining the structure of an object from X-ray photographs. At present, in addition to this X-ray tomography, several other tomographies are also known, where instead of X-ray photographs some other spectral data are used. In addition, tomographical problems are very much related with problems of inverse scattering. All these problems arise in medical imaging, non-destructive testing and different domains of physics. The objective of this course is to give an introduction to the mathematics of this research domain.
The following topics will be considered, in particular:
- X-ray transmission tomography and the classical Radon transform.
- Non-abelian Radon transforms and their applications.
- Inverse scattering for the multidimensional Schrödinger equation.
