Detection device and detection system for medical accelerator

Abstract

The invention provides a detection device and detection system for a medical accelerator. The detection device comprises a first fixed portion, a second fixed portion, a first sliding portion, at least one first driven wheel, a second sliding portion, at least one second driven wheel, at least one driving wheel, a mounting bracket, a third fixed portion, a third sliding portion, a fourth fixed portion, a fourth sliding portion and an ionization chamber, wherein the first fixed portion and the second fixed portion are located at two sides of the bottom end of an accelerator support respectively, the first sliding portion is slidably connected with the first fixed portion; the at least one first driven wheel is installed at the first sliding portion, the second sliding portion is slidably connected with the second fixed portion, the at least one second driven wheel is installed at the second sliding portion, the at least one driving wheel is installed at the second sliding portion, the mounting bracket is connected with the first sliding portion and the second sliding portion, the third fixed portion is mounted at the top end of the mounting bracket and parallel to a horizontal plane, the third sliding portion is slidably connected with the third fixed portion, the fourth fixed portion is installed at the third sliding portion and vertical to the third sliding portion, the fourth sliding portion is slidably connected with the fourth fixed portion, and the ionization chamber is installed at the bottom end of the fourth sliding portion and acquires radiation data of the accelerator. With the detection device and detection system provided by the invention adopted, harm to testing personnel can be reduced, and real-time detection for the medical accelerator can be realized.

Description

Technical field [0001] The invention relates to the field of physics, in particular to a detection device and system for a medical accelerator. Background technique [0002] There is no dedicated automatic measurement equipment in the field of high-energy ray radiation measurement in China. The current measurement method is to manually use the tooling to fix the ionization chamber and then the lead wire enters the operation room for data measurement. This method has low test efficiency, low data measurement accuracy, and real-time In addition, the current high-dose radiation dose testers on the market cannot store the collected data. At the same time, testers also need to frequently enter and exit the accelerator room with extremely large radiation doses, and the potential danger of personal radiation injury is greater. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a detection device and system for a medical accelerato...

[0002] In the field of high-energy ray radiation measurement in China, there is no dedicated automatic measurement equipment. The current measurement method is to manually use tooling to fix the ionization chamber and then lead wires into the operating room for data measurement. This method has low test efficiency and low data measurement accuracy. Real-time In addition, the high-dose radiation dose testers currently on the market cannot store the collected data.

At the same time, the test personnel also need to frequently enter and exit the accelerator room with a high radiation dose, and the potential risk of radiation injury to personnel is relatively high.
