- While the physical key ingredients for PAI imaging are optimal sensors and setups, the mathematical key tools in PAI research involve inversion techniques, reconstruction formulas and filtering techniques, which can be implemented efficiently in software. The applied mathematics group contributes to this research network on PAI with mathematical modelling and simulation, novel reconstruction formulas, filtering techniques and efficient computational algorithms. The developed methods are implemented as computer software which is used by the physicists designing new experimental setups and by the medical doctors and biologists performing experiments. Moreover, mathematical modelling of the next generation PAI scanner technology, which takes into account attenuation and acoustic inhomogeneities, is planned.
