Embodiment Construction

[0033] The invention is a quality control system for radiotherapy equipment, which is an auxiliary system specially used for measuring the light field index of medical radiotherapy equipment such as medical linear accelerator and cobalt-60 treatment machine. The radiation emitted by the radiation therapy equipment is irradiated vertically on the sliding panel of the system locator, and the stepper motor is controlled by the computer to drive the probe on the sliding panel to slide horizontally, so as to collect the information of the radiation output and send it to the dosimeter to measure the radiation therapy equipment. The illumination field index mainly includes the coincidence and uniformity of the light field and the penumbra. Among them, the computer control terminal and dosimeter are placed in an independent room, and the locator and radiotherapy equipment are placed in another isolated room, so that operators can perform detection operations efficiently and safely.

Abstract

The invention discloses a quality control system and a method for a radiotherapy device. The quality control system comprises a control terminal connected to a host computer for outputting a control command to the master machine; the host computer for controlling the operation of an orientator connected to the host computer based on the control command; the orientator for operating based on the control command, collecting the output quantity of the radiotherapy device and transmitting to a dose meter; and the dose meter for detecting the output quantity of the radiotherapy device collected bythe radiotherapy device. Accordingly, the invention further discloses a quality control method for the radiotherapy device. By adopting the orientator to collect the output quantity of the radiotherapy device, the artificial measuring error is reduced, the measurement time is shortened, the working efficiency is improved, and the operating staff is safe from the radiation hazard.

Description

technical field [0001] The invention relates to the field of control and detection of medical equipment, in particular to a control system and method for radiotherapy equipment. Background technique [0002] Radiation therapy is an important means of tumor treatment and one of the rapidly developing disciplines. The improvement of radiotherapy technology and the improvement of curative effect are closely related to the progress of equipment. As a radiotherapy device, the precision requirements are very high, and its performance and precision directly affect the final effect of radiotherapy. Especially the application of the current precise radiotherapy method requires higher accuracy of radiotherapy equipment. Therefore, the configuration of high-performance and high-precision radiotherapy equipment is the basis of radiotherapy, and the daily maintenance, maintenance, detection and adjustment of these radiotherapy equipment It is the protection of radiation therapy. In pa...
