[0003] In the process of realizing the present invention, the inventors of the present invention have found that in the existing dose monitoring system, X-rays or electron beams need to pass directly through the ionization chamber during the dose monitoring process, and part of the beam line will be lost in the process, resulting in dose The reduction of transmission efficiency; on the other hand, for the new type of electron wire post-loading equipment, the electron beam is transmitted in a stainless steel (or other material) tube during the whole process from the accelerating tube to the tumor, and cannot directly pass through the ionization chamber, so the ionization chamber does not not suitable for this device

The present invention relates to the field of accelerator technology, and in particular discloses a dose monitoring method, device, equipment, control system and computer storage medium of a medical accelerator, wherein the equipment includes: a particle accelerator, the particle accelerator includes an acceleration tube connected to the outlet of the acceleration tube The beam pipeline; the sensor, the sensor is arranged on the periphery of the beam pipeline, and generates a signal reflecting the charge of the particle beam in real time through inductive or capacitive coupling; the processing unit, the processing unit obtains the corresponding dose according to the parameters of the current pulse signal. It can be seen that, using the solution of the present invention, the dose of the beam pulse output by the accelerator can be monitored in real time, so that the dose entering the patient's body can be controlled to achieve a therapeutic effect while ensuring the safety of the patient.
Description
technical field [0001] The present invention relates to the technical field of medical accelerators, in particular to a method, device, medical equipment, control system and computer storage medium for dose monitoring of medical accelerators. Background technique [0002] According to the requirements in the regulations GB9706.5-2008, the dose monitoring system must be included in the medical electron linear accelerator. The dose monitoring system used in traditional medical accelerators consists of ionization chamber detectors and their auxiliary circuits. The ionization chamber is located in the radiation system, installed between the uniform filter or the scattering foil and the secondary collimator of the photon line, and is composed of several pole pieces, two of which are used to monitor the radiation field. For the uniformity of the direction, one is used to monitor the energy change of the radiation, and two are used to detect the absorbed dose of the radiation. Mo...
