Non-range type digitalized medical linear accelerator system with electronic wire energy gears

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.

Problems solved by technology

Generally speaking, the accelerator provided by the manufacturer has multiple (3-5) electronic wires, and the energy of each electronic wire is calibrated when the equipment leaves the factory, and the user cannot change it when using it.

In actual use, due to the relatively large individual differences in the depth and position of tumors, it is difficult for physicists to directly treat patients with calibrated electronic wires, and often need to use biological compensation glue to compensate for the treatment Depth adjustment is more complicated to use

Moreover, often due to the poor matching between the energy and the actual tumor depth, when treating patients, either the energy is too large, which damages healthy body parts, or the energy is insufficient, so that the tumor cannot be treated in time and effectively, prolonging the life expectancy of the patient. Healing time, serious even delayed the patient's treatment timing,
