A radiotherapy device, comprising a bed (7-2), a radiation exposure head (10), a head oscillating mechanism, a precision inspection device (30), and a control part, wherein the radiation exposure head (10) radiates radioactive ray (3a) for therapy to the treated field of a subject (4), the head oscillating mechanism oscillates the radiation exposure head (10) so that the radioactive ray (3a) for therapy injected from the radiation exposure head (10) can follow up the movement of the treated field, the precision inspection device (30) acquires a diagnostic image, and the control part (80) controls the head oscillating mechanism so that the radiated field of the radiation exposure head (10) can follow up the treated field based on the diagnostic image, position of the radiation exposure head (10), and oscillated state of the radiation exposure head (10) and, after controlling the head oscillating mechanism, also controls the radiation exposure head (10) so as to radiate the radioactive ray (3a) for therapy from the radiation exposure head (10).
L'invention porte sur un appareil de radiothérapie comprenant un lit (7-2), une tête (10) d'application des radiations, un mécanisme d'oscillation de la tête, un dispositif d'inspection (30) de précision, et un élément de commande. La tête émet des rayons (3a) de radiothérapie sur la partie à traiter d'un patient (4); le mécanisme oscillant permet à la tête de suivre les mouvements de la partie à traiter, le dispositif d'inspection (30) capte un image diagnostique, et l'élément de commande (80) commande le mécanisme oscillant pour que la tête (10) suive les mouvements de la partie à traiter en fonction de l'image captée, de la position de la tête (10) et de son état d'oscillation, et, après avoir commandé le mécanisme oscillant, commande la tête (10) pour qu'elle émette les rayons (3a) de radiothérapie
