SPECT reconstruction with a transformed attenuation prototype at multiple levels

In this work, a novel multilevel approach to Single Photon Emission Computed Tomography (SPECT) reconstruction based on a so-called transformed attenuation prototype is presented. As our results indicate, the benefits of a multilevel strategy as known from literature can be observed as well. That is, we show results where a local minima of a single level reconstruction is avoided and a more preferable SPECT reconstruction is obtained.
