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 radioactive source 6 is installed in the radioactive source hole 4; the switch body 2 is a plurality of cylinders installed in the radioactive source body 1, and a rotating drive is installed on the top of each cylinder 2 Device 7, an intermediate collimating hole 8 is installed on the cylinder 2; the final collimating body 3 is installed in the radiation source body 1, and a final collimating hole is installed on the final collimating body 3 9.

[0010] Because the present invention adopts the above technical scheme, the structure is simple and light, and the cost is low. The rotation of each cylinder 2 can be controlled separately by rotating the driving device ...

Abstract

The invention relates to a medical radiotherapeutic device, 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 rotation driving device is respectively 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 cost is low, 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]...
