摘要:
A radiotherapy system comprising at least one pulsed radiation source, at least one imaging system, a control system, and a synchronization system is disclosed. The pulsed radiation source deposits high dose radiation pulses to a target region inside the patient; simultaneously the imaging system is used to monitor the target region, synchronized by the synchronization system. The dose per radiation pulse is high enough to deposit, within few pulses, 1 Gy at a depth of at least 1 cm in water. At each irradiation time step, the pulsed radiation source delivers short pulses of radiation (<;1 ms) and the imaging system performs a snapshot of the position, and eventually the shape, of the target region during the irradiation time, with a time resolution better than 200 ms. Being both the pulsed radiation source and imaging system synchronized by the synchronization system with less than 200 ms jitter, this system allows for very precise reconstruction of the map of the dose deposited into the target region.
