Abstract

L’invention concerne un ensemble de collimation (3) pour détecteur (20) de rayonnement gamma. L’ensemble de collimation (3) comprend au moins deux collimateurs (6). Chacun des collimateurs (6) est configuré pour être mobile au moins en translation le long d’un axe longitudinal de détection (X-X) relativement au détecteur (20) et relativement à l’autre des collimateurs (6). Figure pour l’abrégé : figure 1The invention relates to a collimation assembly (3) for a gamma radiation detector (20). The collimation assembly (3) includes at least two collimators (6). Each of the collimators (6) is configured to be movable at least in translation along a longitudinal detection axis (X-X) relative to the detector (20) and relative to the other of the collimators (6).
