A method of computing tomographic images from single photon radionuclide emission data ... The method takes into account attenuation of gamma rays inside the source and makes use of iterative technique, based on the difference between the projection data obtained from the source and computed projections, called reprojections, from successive reconstructions of the sources. 1, record 1, English, - gamma%20emission%20computed%20tomography

Pour la tomographie par émission gamma (TEG), les principaux problèmes, dont certains sont communs à d'autres types de tomographie (rayons X, positrons), sont : l'auto-atténuation, la collimation, les statistiques de comptage et l'échantillonnage. 2, record 1, French, - tomographie%20par%20%C3%A9mission%20gamma

The problems with projection imaging can be overcome by acquiring tomographic data with a rotating gamma camera and then correcting for attenuation in a tomographic reconstruction. This method is called single-photon emission computed tomography(SPECT). 1, record 2, English, - rotating%20gamma%20camera
