Problems solved by technology

There are defects in the existing measuring water tank: when the measuring depth needs to be changed, the coincidence of the level of the horizontal plane and the depth scale line of the tank is observed by the human eye. Often different people, or even the same person at different times, have different eye positions to see The height of the water surface is also different, which artificially causes measurement errors, and the existing water tank can only be measured for a specific height of the water level, resulting in measurement limitations

Abstract

The invention discloses a one-dimensional water tank for measurement of a radiotherapy machine. The water tank comprises a first box body, an ionization chamber adapter, a drainage hose and a water level device. The ionization chamber adapter is arranged in the first box body; the ionization chamber adapter is provided with an accommodating cavity penetrating to a side wall of the first box body;the accommodating cavity is used for accommodating an ionization chamber; a drainage hole is formed in the side wall of the first box body, the first end of the drainage hose is connected with the drainage hole, a water outlet platform is arranged at the second end of the drainage hose, a plurality of grooves are arranged in a water level indicator, each groove has a preset height, and the groovesare used for containing the water outlet platform so that the upper surface of the water outlet platform has a preset height. According to the one-dimensional water tank for measurement of the radiotherapy machine, limitation of water surface height measurement in the first tank body is solved, an operator does not need to observe a water surface height through eyes when the one-dimensional watertank is used, measurement time is shortened, and manual measurement errors are reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a one-dimensional water tank used for measuring radiation therapy machines. Background technique [0002] At present, tumor radiotherapy is a treatment method that uses high-energy X-rays to deal with tumor cells through the focusing of the rays. The energy and dose of high-energy rays will change, and the ionization chamber and measuring water tank must be used to quantitatively detect high-energy X-rays, which is a necessary step to ensure accurate tumor radiation therapy doses. [0003] In the existing common water tank, radiotherapy physicists place the measurement center of the ionization chamber in the water tank at the central axis of the ionization chamber adapter, and then fill the water tank to different depths for radiation energy measurement and radiation dose calibration. There are defects in the existing measuring water tank: when the measuring depth ne...
