  12. The object of single photon emission computed tomography ( spect ) is to reconstruct an unknown radioactivity distribution inside the body from projection data consisting of the number of photon collected on a collimated gamma camera. these projections are not simple line integrals but have point - spreads due to the imperfect collimator of the detector and attenuation due to the compton scattering. so
