Abstract

L'invention concerne les appareils destinés à former des tomogrammes sous l'action des radiations d'isotopes radioactifs. Elle se rapporte à un appareil comprenant dix détecteurs de radiations ayant des collimateurs très focalisés, assurant le balayage d'un champ d'analyses, les détecteurs formant deux groupes de- cinq, un groupe se rapprochant du champ de balayage lorsqu'un groupe s'en éloigne. L'ensemble des détecteurs tourne d'un angle correspondant à la moitié de l'espacement angulaire des détecteurs afin que le nombre de données collectées soit doublé. Application à la réalisation de tomogrammes pour le diagnostic médical.
