Problems solved by technology

[0006] During the above operation process, the operator’s manual operation is completely exposed to the gamma ray radiation of rod source 03, the radiation intensity is generally 2-5mCi, which will cause damage to the operator who has been engaged in PET and CT scanning for a long time
[0007] In addition, the efficiency of the above-mentioned purely manual operation process is low, and there are large operating errors in manual operation, and the reliability of rod source installation is low, which is not conducive to improving the calibration efficiency

Abstract

The invention provides a scanning device of a medical detector and an automatic assembling and disassembling device for a medical rod source. By the aid of the scanning device and the automatic assembling and disassembling device, the assembling and disassembling efficiency and precision can be improved, and radiation damage caused by manual operation can be prevented. The automatic assembling and disassembling device comprises a screw which is parallel to the axial direction of the rod source and a nut base which is in threaded connection with the screw, the circumference of the nut base is fixed, and an electromagnet is arranged on the nut base, so that the rod source can be connected or separated through control of energization and deenergization of the electromagnet. When a rod is required to be fed, the electromagnet is energized or deenergized, the rod source is positioned by the electromagnet, then the screw is driven to rotate in a forward direction, and the nut base drives the electromagnet on the nut base and the rod source to move with the nut base along the axial direction of the screw, so that the rod source is pushed to move towards the detector and finally sent into the detector. By the aid of the structure, the automatic assembling and disassembling of the rod source is achieved, the radiation damage caused by manual operation is prevented, the operation precision is high, and the reliability of rod source installation is improved.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to an automatic loading and unloading device for medical rod sources. Background technique [0002] At present, PET (positron emission tomography, positron emission tomography) and CT (computed tomography, motor computer X-ray tomography) technologies are widely used in the field of medical technology. Usually, before the use of PET and CT products, a normalized calibration scan is required to scan the rod source through its rod source to achieve the gain setting of the rod source, so that the rod source can work in the best state and reduce the cost caused by detector manufacturing and assembly. Image artifacts caused by errors can improve the image quality acquired by rod sources. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of a three-dimensional structure of a rod source inserted into a detector in a specific embodiment in the prior art. ...
