Method for treating a target volume with a particle beam and device implementing same
First Claim
1. Process for treating a particle beam (1000) produced by an accelerator in order to irradiate a target volume (0) consisting of for example a tumor to be treated in the case of a cancer, wherein this particle beam (1000) is produced using said accelerator, and a spot (100) located in the target volume is formed from this beam, characterized in that the movement of said spot within the target volume along the three dimensions (X, Y, Z) and the variation of the particle beam intensity are performed simultaneously so that the dose to be delivered conforms to the target volume.

Abstract
The invention concerns a method for treating a target volume with a particle beam, in particular a proton beam, which consists in generating said particle beam using an accelerator and in producing from said beam a narrow spot directed towards the target volume, characterized in that said spot sweeping speed and the particle beam intensity are simultaneously varied.

- 19. Process for treating a particle beam (1000) produced by an accelerator and devoted to the irradiation of a target volume (0) consisting of for example a tumor to be treated in the case of a cancer, wherein the particle beam is produced using a fixed-energy accelerator, and a narrow spot directed towards the target volume is produced from this beam, characterized in that the energy of said particle beam is modified immediately after it is extracted from the accelerator, wherein the movement of a spot (100) within the target volume and the variation of the particle beam intensity are performed simultaneously so that the dose to be delivered conforms to the target volume.
