While the aim of CT is the reconstruction of real objects from their actual x-ray projections, the theoretical development of CT owes a lot to reconstruction of mathematically described objects (phantoms) from computer simulated projection data. The basic reason for this is that computer simulation enables us to investigate individually various phenomena that cannot be separated physically. For example, x-ray data always contain noise due to both photon statistics and scatter, but simulation can indicate the specific separate effects of noise and scatter.
