Method and Irradiation Installation for Irradiating a Target Volume

摘要

The present disclosure relates to a method and to an irradiation system for irradiating a moving target volume with an ion beam, in particular for tumor therapy, wherein ion radiography measurements of the target volume are performed and the irradiation for deposition purposes and for radiography purposes is performed with the same ion beam but consecutively in time by alternating the energy of the ion beam between a higher radiography energy and a lower deposition energy using, for example, a passive energy modulator proximal with respect to the patient.

主权项

1. A method for irradiating a target volume with an ion beam;
wherein the irradiation of the target volume is divided over time into at least one radiography phase and at least one deposition phase; wherein the energy of the ion beam is altered over time between the at least one radiography phase and the at least one deposition phase, such that i) in the at least one radiography phase, the range of the ion beam is distal with respect to the target volume, so that the ion beam passes through the target volume, and wherein by means of the ion beam an ion radiograph of the target volume is acquired by detecting the ion beam with an ion radiography detector that is arranged distal with respect to the target volume; and ii) in the at least one deposition phase, the range of the ion beam is within the target volume, so that the ion beam is stopped in the target volume to deposit a predetermined dose in the target volume.
