Abstract

Structure permettant de former des images sous un certain angle par rapport à l'axe de translation du corps du patient. Elle comprend deux organes en forme de L 25 à 28, deux segments incurvés 23, 24, deux montants 21, 22, portant des jeux de galets supportant les segments incurvés, des moyens de support fixés aux branches verticales 26, 28 des organes en forme de L, des moyens formant poulie tournant sur les moyens de support, une base tournante 31 fixée aux moyens formant poulie et portant une source de rayons X 39 et des moyens de détection 42, des moyens pour entraîner les moyens formant poulie en rotation, et des moyens pour entraîner les segments sur les galets afin de faire basculer les organes en forme de L. Application à la tomodensitométrie.
