IMA Workshop
Computational Radiology and Imaging: Therapy and Diagnosis
March 17-21, 1997

Mathematics of High Performance Computing
Molecular Modeling and HPC

Organizers:

Christoph Borgers (Tufts University) and Frank Natterer (Univ. of Münster, Germany)

Radiation is used in medicine for both diagnostics (for instance, tomography) and therapy (for instance, radiation treatment of cancer). These applications lead to hard computational and mathematical problems. From a mathematical point of view, many of these are related to differential or integro-differential equations. As an example, Boltzmann transport equations underlie the modeling of optical tomography and radiotherapy planning. Typically, inverse problems are the ones of ultimate interest, but even the forward problems are often quite difficult computationally.

The workshop brings together Applied Mathematicians, Numerical Analysts, Nuclear Engineers, and Medical Physicists working on different aspects of these and related problems, including subjects such as X-ray tomography and magnetic resonance imaging. One of the main purposes of the workshop is to improve communication between different groups of researchers working on different aspects of the same problems, sometimes without even knowing about each others' existence. There will therefore be a substantial number of expository talks aimed at non-specialists.
