Medical X-ray CT dose measurement model

Abstract

A medical X-ray CT dose measurement model disclosed by the present invention comprises a display box, a rotating mechanism, a supporting mechanism and moving wheels, the rotating mechanism is installed on the supporting mechanism, the supporting mechanism is rotatably connected with the display box through the rotating mechanism, a shock absorber is installed at the bottom of the supporting mechanism, and the moving wheels are installed at the bottom of the shock absorber. According to the medical X-ray CT dose measurement model, through arrangement of the rotating mechanism, the height of the display box can be adjusted, the purpose of improving the demonstration effect is achieved, through arrangement of a rolling frame, a gear ring, a first motor, a gear and a lifting adjusting mechanism, the purpose of preventing a head mold from being damaged is achieved, the service life of the head mold is prolonged, and the practicability of the medical X-ray CT dose measurement model is improved. The lead plate and the sliding door are lead-containing anti-radiation glass, so that radiation generated by X-rays is prevented from hurting a human body during demonstration, and movement and carrying are facilitated through the arrangement of a shock absorber and moving wheels.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a medical X-ray CT dose measurement model. Background technique [0002] In radiation research work, the dose must be determined accurately, otherwise the correct radiation chemical yield cannot be obtained, and the reaction process is difficult to control and reproduce. In radiation processing, it is also required to determine the dose more accurately, otherwise the irradiated sample is not If the expected effect is not achieved, it will be scrapped in batches. At the same time, dosimetry is also very important in radiation protection. [0003] The existing medical X-ray CT dose measurement model needs to be used directly on the CT machine. When demonstrating to personnel, there are the following problems: 1. Operations such as installation, plugging, etc. must be performed every time the measurement demonstration is performed, and the long rod The ionization chamber is easy ...

AI Technical Summary

Problems solved by technology

[0003] The existing medical X-ray CT dose measurement model needs to be used directly on the CT machine. When demonstrating to personnel, there are the following problems: 1. Operations such as installation, plugging, etc. must be performed every time the measurement demonstration is performed, and the long rod The ionization chamber is easy to collide with the inner hole wall of the head mold during installation, resulting in damage to the inner hole wall of the head mold. Second, it is inconvenient to adjust the height and angle of the measurement model during demonstration, which affects the demonstration effect. Third, X-rays have certain Radiation, requires external protection, the conventional protection volume is large and heavy, which makes the model inconvenient to move and carry during the demonstration
