摘要：
The present invention relates to a positron emission tomography device for capturing an image of an object to be examined by using positrons, and comprises: a frame a mobile plate which is a planar member having a central hole, and is able to perform parallel-travel movement in the X direction and the Y direction and rotational movement in the Z direction with respect to the frame detection modules, of which a plurality are joined to the mobile plate, in a state disposed around the circumference of the central hole and three parallel-travel mobile units which respectively produce parallel-travel movement in specific directions over the X-Y surface, in three points of the mobile plate that are separated from each other. The three parallel-travel mobile units are disposed in such a way that the mobile plate can simultaneously perform respectively independent X-direction and Y-direction parallel-travel movements and Z-direction rotational movements with respect to the frame. According to the present invention, there is the advantage that sampling intervals in each of the axial directions are made more dense as the mobile plate can simultaneously perform respectively independent X-direction and Y-direction parallel-travel movements and Z-direction rotational movements.La présente invention concerne un dispositif de tomographie par émission de positons destiné à capturer une image dun objet à examiner à laide de positons, qui comprend : un châssis une plaque mobile qui est un élément planaire ayant un trou central, et est capable de réaliser un mouvement de déplacement parallèle dans la direction X et dans la direction Y et un mouvement rotatif dans la direction Z relativement au châssis des modules de détection, plusieurs dentre eux étant fixés à la plaque mobile, et disposés autour de la circonférence du trou central et trois unités mobiles à déplacement parallèle qui produisent respectivement un mouvement de déplacement parallèle dans des directions spécifiques sur
