INTRA-OPERATORY CARBON ION RADIATION THERAPY SYSTEM

摘要

An ion therapy system for irradiating a patient with laser-accelerated ions may include a laser radiation source to emit laser radiation and a housing coupled to the laser radiation source. The system may have a laser target having a surface from which an ion beam can be generated. The housing may have a window portion to let an incident ion beam pass and to seal the housing. The system may have a vacuum system to generate lower pressure in the inner space of the housing. A focusing system may focus the laser radiation on the laser target. A control device may control the focusing system and adjust a propagation direction of the ion beam such that the ion beam impinges on an external target. The laser radiation source may generate laser pulses with a duration between 10−18 seconds and 10−12 seconds and an energy of at least 100 mJ.

1. An ion therapy system for irradiating a patient with laser-accelerated ions, comprising:
a laser radiation source to emit laser radiation; a housing, comprising an inner space, coupled to the laser radiation source; a laser target having a surface from which an ion beam is to be generated; a window portion in the housing, wherein the window portion is to let an incident ion beam pass the window portion to an outside of the housing, and wherein the window portion is further to seal the housing; a vacuum system to generate a lower pressure in the inner space of the housing than the outside of the housing, a focusing system to focus the laser radiation on the laser target; a holder to hold the laser target; and a control device to control the focusing system and the holder to adjust a propagation direction of the ion beam such that the ion beam impinges on an external target, wherein the laser radiation source is to generate laser pulses with a duration between 10−18 s and 10−12 s and an energy of at least 100 mJ.
