Abstract

The invention relates to a multi-leaf collimator control system, comprising an industrial control computer, and a main controller connected with the industrial control computer, wherein the main controller is connected with a blade and cabinet controller which controls and connects with a blade and cabinet driver; the blade and cabinet driver is in driving connection with a blade and cabinet motor which is in transmission connection with a blade and a cabinet body; the blade and the cabinet body are provided with position detectors which are connected with the blade and cabinet controller to form a feedback loop; and the driver is connected with the blade and cabinet controller by a current detector to form a feedback loop. The multi-leaf collimator control system is controlled by the industrial control computer, realizes the closed-loop feedback adjustment by using an encoder or a linear scale, and improves running precision of the blade and the cabinet body; moreover, the control process is stable, reliable, convenient and rapid.

Description

technical field [0001] The invention relates to the technical field of medical electronics, and more specifically, relates to a multi-leaf collimator control system. Background technique [0002] As the auxiliary equipment of medical electron linear accelerator or cobalt 60 machine, the multi-leaf collimator has the functions of automatic conformation and intensity modulation. During use, the user operates it through computer and other control equipment, and the realization of the control process Rely on its set of control system, therefore, the performance of the multi-leaf collimator depends on the quality of the control system. [0003] The control object of the control system of the multi-leaf collimator provided by the prior art is limited to a small number of leaves, the box is fixed, the radiation field formed is often small, the degree of automation is poor, the control method is relatively backward, and the operation is not good. Convenience. Contents of the inve...
