Abstract
A collimator for tomoscintigraphy comprising several juxtaposed sets of adjacent parallel tubes each positioned for each receiving transverse radiation at a different incidence angle from an individual organ under observation, thereby permitting with each step of rotation of a gamma camera, selective registration of information corresponding to as many images as there are sets in the collimator.
