Abstract
L'invention concerne les caméras à scintillation. Le collimateur 4 correspondant à l'invention est constitué par un corps en une substance qui arrête le rayonnement gamma, muni de bandes 7 formant un réseau de fentes. Ces fentes n'assurent un effet de collimation que dans une seule direction, et l'analyse de l'objet s'effectue en faisant tourner rapidement le collimateur autour d'un axe perpendiculaire au plan du détecteur de la caméra à scintillation. Application à la tomographie.
