Michel Defrise (Vrije Universiteit, Brussel): Statistical reconstruction methods in medical imaging
Statistical reconstruction methods are probably today the most common methods to obtain tomographic images from SPECT/PET measurements. The methods are based on modelling the camera systems and thereby iteratively find a good estimate of the internal radionuclide distribution from the similarity of the calculated and measured projection data. The main advantage is here that if physical problems, associated with the measurement of the radiation, such as, non-homogeneous photon attenuation, contribution from scattered photons, partial volume problems due to collimator resolution, septal penetration etc, can be modelled accurately then this naturally comes out as a compensation for the problems. The lecture will cover the fundamental mathematical parts of the procedures describe above.
