Abstract
L'invention concerne un appareil de tomographie. Une source de rayons X émet un éventail de rayonnements. On fait en sorte que les rayons prennent une série de positions angulaires différentes sans changer l'origine de l'éventail. Puis, on décale cette origine. Les détecteurs de rayons X se meuvent relativement à l'étalement pendant la premiere phase de façon que les détecteurs successifs reçoivent des rayons suivant chacun des parcours de faisceau. Application : diagnostic médical.
