Embodiment Construction

[0031] The present invention is a quality control system for radiotherapy equipment, which is an auxiliary system specially used for measuring the light field indicators of medical radiotherapy equipment such as medical linear accelerators and cobalt-60 therapeutic machines. The radiation emitted by the radiotherapy equipment is irradiated vertically on the sliding panel of the system locator, and the probe on the sliding panel is driven to slide horizontally by the computer controlled stepping motor, so as to collect the information of the ray output and send it to the dosimeter to measure the radiotherapy equipment. The index of the light field mainly includes the coincidence and uniformity of the light field and the penumbra. The computer control terminal and the dosimeter are placed in a separate room, and the locator and radiotherapy equipment are placed in another isolated room, so that the operator can efficiently and safely perform detection operations.

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 by the 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 quality control and detection of medical equipment, in particular to a quality control system and method for radiotherapy equipment. Background technique [0002] Radiotherapy is an important means of tumor treatment, and it is one of the rapidly developing disciplines. The improvement of radiotherapy technology and the improvement of curative effect are closely linked with the advancement of equipment. As a radiotherapy equipment, the accuracy requirements are very high, and its performance and accuracy directly affect the final effect of radiotherapy. In particular, the application of current precision radiotherapy methods requires higher accuracy of radiotherapy equipment. Therefore, the configuration of high-performance, high-precision radiotherapy equipment is the basis of radiotherapy, and the daily maintenance, maintenance, inspection and adjustment of these radiotherapy equipment It is a guarantee for radiothera...
