Abstract

The invention discloses a non-range type digitalized medical linear accelerator system with electronic wire energy gears. The hardware of the system comprises an industrial control computer, a special data communication device and a head healing device; the software comprises a parameter setting module of a modulator, an automatic beam current control (AIC) module, an automatic frequency control (AFC) module, an automatic dosage control (ADC) module, an accelerating tube distribution control module, a head healing scattering film selection control module, a dosage evaluation and calibration module and a heating module; the parameter setting module of a modulator, the AIC, the AFC, the ADC, the accelerating tube distribution control module and the head healing scattering film selection control module are respectively within a range of 6MeV-16MeV; according to refine range level and actual preset values of adjacent two fixed energy gears, corresponding values are obtained at regular intervals; according to the above modules, after the dosage evaluation and calibration module obtains a series of values required by the digitalized medical accelerator at a preset range, the dosage evaluation and calibration module carries out evaluation and calibration on dosage in accordance with preset standards; and if the dosage is within a normal range, the related information is sent to an executing mechanism of peripheral equipment for execution. When the non-range type digitalized medical linear accelerator system with electronic wire energy gears is utilized to treat patients, the matching degree of energy and tumour depth is improved, and a more accurate therapeutic schedule is formulated for each patient.
