Abstract

The invention provides radiation treatment equipment and a dosage control apparatus and method thereof. The dosage control apparatus comprises a microwave pulse generator, an electron injector, an accelerating tube, a time-delay controller and an X-ray conversion apparatus, the microwave pulse generator generates a microwave pulse, the electron injector generates an electronic pulse, the accelerating tube introduces the microwave pulse and the electronic pulse and accelerates the electronic pulse according to the microwave pulse, the time-delay controller is configured to control the relativetime delay of the microwave pulse from the microwave pulse generator and the electronic pulse from the electron injector to enable the relation between the microwave pulse and the electronic pulse toat least comprise both partial synchronous states, and the X-ray conversion apparatus converts injected electrons after acceleration of the accelerating tube to X-ray dosage.

Description

technical field [0001] The present invention mainly relates to the field of radiotherapy equipment, in particular to a dose control device and method. Background technique [0002] Radiotherapy is the use of modern high-tech computers to control the advanced ray generation equipment - medical electron linear accelerator, by controlling the incident direction of the radiation, the radiation area to the tumor without surgery, painless, less damage, less effective tumor treatment plan . [0003] For radiotherapy devices, the generation of high-energy electrons is achieved by injecting pulses of electrons in the accelerating phase of the microwave. The high-energy electrons pass through the target (ie, the therapeutic target) to generate radiation that irradiates the tumor tissue. The radiation dose absorbed by the tumor tissue, the absorbed dose, is a concern in radiation therapy. In the radiotherapy of tumors, a given absorbed dose should be deposited in a given tumor targe...
