Title
(EN) IMAGING DEVICE
(FR) DISPOSITIF D'IMAGERIE
Abstract
(EN) An imaging device (1 ) comprising a gantry (2) defining an analysis zone (2a) suitable to contain the portion of patient to be examined and a circular trajectory of extension (2b) extending around a central axis (2c); the gantry (2) comprises an acquisition unit comprising at least a detector (21 ) suitable to receive said radiation after said radiation has passed through the analysis zone (2a); and a casing (23) defining a housing volume for the detector (21 ) and comprising a curved base module (231 ) and a curved mobile module (232a, 232b) movable relative to the curved base module (231 ) so as to vary the angular extension of the casing (23); the gantry (2) comprises, housed in the housing volume, a carriage (24a, 24b) to which the image acquisition unit is attached; a base guideway (25) integral with the curved base module (231 ) and defining a base sliding trajectory (25a) for the carriage (24a, 24b) in the curved base module (231 ); and a mobile guideway (26) integral with and inside the curved mobile module (232a, 232b) and defining a mobile sliding trajectory (26a) for the carriage (24a, 24b) in the curved mobile module (232a, 232b).
(FR) On décrit un dispositif d'imagerie (1) qui comprend: un portique (2) délimitant une zone d'analyse (2a) pouvant contenir la partie du corps d'un patient à examiner; et une trajectoire circulaire d'extension (2b) s'étendant autour d'un axe central (2c). Le portique (2) comprend une unité d'acquisition comprenant au moins un détecteur (21) approprié pour recevoir ledit rayonnement après que celui-ci a traversé la zone d'analyse (2a); et un boîtier (23) délimitant un volume de boîtier pour le détecteur (21) et comprenant un module de base courbe (231) et un module mobile courbe (232a, 232b) qui se déplace par rapport au module de base courbe (231) de manière à faire varier l'extension angulaire du boîtier (23). Le portique (2) comprend: un chariot (24a, 24b) logé dans le volume de boîtier et auquel l'unité d'acquisition d'image est fixée; un rail de guidage de base (25) solidaire du module de base courbe (231) et délimitant une trajectoire de coulissement de base (25a) pour le chariot (24a, 24b) placé dans le module de base courbe (231); et un rail de guidage mobile (26), logé dans et solidaire du module mobile courbe (232a, 232b), qui délimite une trajectoire de coulissement mobile (26a) pour le chariot (24a, 24b) placé dans le module mobile courbe (232a, 232b).
