The present relates to a device for providing a radiation treatment to a patient comprising: —an electron source for providing a beam of electrons, and —a linear accelerator for accelerating said beam until a predetermined energy, and —a beam delivery module for delivering the accelerated beam from said linear accelerator toward the patient to treat a target volume with a radiation dose, The device further comprises intensity modulation means configured to modulate the distribution of the radiation dose in the target volume according to a predetermined pattern. The pattern is determined to match the dimensions of a target volume of at least about 50 cm, and/or a target volume located at least about 5 cm deep in the tissue of the patient with said radiation dose, The radiation dose distributed is up to about 20 Gy delivered during an overall treatment time less than about 50 ms.

Device for providing a radiation treatment

The present relates to device for ultra-high dose rate radiation treatment to a patient, comprising: —a radiation source for providing a radiation beam, and—a linear accelerator for accelerating said radiation beam until a predetermined energy, and—a beam delivery module for delivery the accelerated radiation beam. The device is arranged for generating an accelerated radiation beam having a predetermined energy between about 50 MeV and about 250 MeV, to deliver rate radiation dose of at least 10 Gy, during an overall time less than about 200 ms in order to generate a radiation field for treating a target volume of at least about 30 cm3, with said ultra-high dose rate radiation dose and/or a target volume located at least about 5 cm deep in the tissue of the patient with said ultra-high dose rate radiation dose.
