Abstract
Image reconstruction is to estimate a spatial distribution of some parameter inside an object from its projections, where projections are a set of measurements of the line integral values of the parameter. The parameter is a linear attenuation coefficient for transmission x-ray CT, while it is a radioactivity level in case of emission computed tomography (CT) such as single photon emission CT (SPECT) or positron emission tomography (PET).
