ABSTRACT:
A radiotherapy device includes: a linac 1 for generating an electron beam 9, and a thin guide tube 2 for guiding the electron beam from the linac 1 to the affected part 7 within the body of the patient 6. The orbit of the electron beam 9 is controlled by means of the feedback circuit 8 in response to the output of the deviation detector 6 which detects the leakage of the electron beam outside of the guide tube 2. A high-level dosage can be accomplished without incurring danger of radiation exposure on the operator.
