Embodiment Construction

[0009] As shown in Figure 1, the structure of the medical radiotherapy device of the present invention is mainly composed of a radioactive source body 1, a switch body 2 and a final collimator 3, and a radioactive source hole 4 and a pre-collimator are installed on the radioactive source body 1. A straight hole 5, a radiation source 6 is installed in the radiation source hole 4; the switch body 2 is a plurality of cylinders installed in the radiation source body 1, and a linear drive is installed on the top of each cylinder 2 Device 7, an intermediate collimation hole 8 is installed on the column body 2; the final collimation body 3 is installed in the radiation source body 1, and a final collimation hole is installed on the final collimation body 3 9.

[0010] Because the present invention adopts the above technical scheme, the structure is simple and light, and the cost is low. Each cylinder 2 can be controlled to move back and forth through the linear drive device 7, causi...

Abstract

The invention relates to a medical radiotherapeutic device structure, which mainly comprises a radioactive source body, a switch body and an end collimation body. A radioactive source hole and a pre-collimation hole are arranged on the radioactive source body, and a radioactive source is arranged in the radioactive source hole; the switch body is to arrange a plurality of cylinders in the radioactive source body, a linear driving device is arranged at the upper part of each cylinder, and a middle collimation hole is arranged on the cylinder; an end collimation body device is arranged in the radioactive source body, and an end collimation hole is arranged on the end collimation body. The invention is of the medical radiotherapeutic device structure that the structure is simple and portable, the switch can be controlled respectively, and the quantity of the radiation can be smartly adjusted.

Description

technical field [0001] The invention relates to a structure of a medical radiotherapy device. Background technique [0002] The structure of a general medical radiation therapy device is mainly composed of a radiation source body, a switch body and a final collimator. Wherein the switch body is a whole, and the middle collimation hole on it deviates from the pre-collimation hole on the radiation source body by shifting, so as to switch the radiation source. However, since this structure will open all the radiation channels if it is to be opened, and will close all the radiation channels if it is to be closed, it is not conducive to flexible adjustment of the radiation amount. [0003] purpose of invention [0004] The object of the present invention is to provide a structure of a medical radiotherapy device with simple and portable structure and low cost, which can control the switches separately and flexibly adjust the radiation dose. Contents of the invention [0005]...
