| Abstract | A particle radiotherapy device, which has a dosage monitoring device (26) that measures particle beam dosage and an ionisation chamber (38) that is smaller than the dosage monitoring device (26), measures the dosage of particle beams passing through the dosage monitoring device (26). The particle radiotherapy device scans the particle beams and irradiates an irradiation position of the irradiation object with the particle beams. The particle radiotherapy device measures the dosage of irradiated particle beams with the dosage monitoring device (26), measures the dosage of particle beams passing through the dosage monitoring device (26) with the small ionisation chamber (38), and on the basis of the dosage of particle beams measured with the small ionisation chamber (38), finds the correction coefficient corresponding to the irradiation position of the dosage measured with the dosage monitoring device (26).
L'invention porte sur un dispositif de hadronthérapie, lequel a un dispositif de surveillance de dosage (26) qui mesure un dosage de faisceaux de particules et une chambre de ionisation (38) qui est plus petite que le dispositif de surveillance de dosage (26), mesure le dosage de faisceaux de particules passant à travers le dispositif de surveillance de dosage (26). Le dispositif de hadronthérapie balaie les faisceaux de particules et irradie une position d'irradiation de l'objet d'irradiation avec les faisceaux de particules. La dispositif de hadronthérapie mesure le dosage de faisceaux de particules irradiés avec le dispositif de surveillance de dosage (26), mesure le dosage de faisceaux de particules passant à travers le dispositif de surveillance de dosage (26) avec la petite chambre d'ionisation (38), et sur la base du dosage de faisceaux de particules mesurés avec la petite chambre d'ionisation (38), trouve le coefficient de correction correspondant à la position d'irradiation du dosage mesuré avec le dispositif de surveillance de dosage (26). |
