Description

Detector disassembly tool

Technical Field

The utility model relates to the technical field of CT equipment, in particular to a detector dismounting tool.

Background

CT machine detectors, also known as X-ray detectors, are a critical component of the computed tomography (comput ed tomography scanning) technology for acquiring tomographic images of a human body or object.

The main function of the CT detector is to receive and measure X-rays after passing through the scanned object. It is typically composed of a series of detector units arranged in a ring-like structure. Each detector unit comprises an X-ray detector and a signal processing unit. X-ray detectors typically employ a scintillation crystal or a gas detector. The scintillation crystal detector consists of a scintillation material and a photomultiplier tube, and when X-rays are incident on the scintillation crystal, visible light signals are generated, and the photomultiplier tube converts the visible light signals into electric signals. The gas detector uses the charge generated by the ionization of the X-rays in the gas to measure the magnitude of the charge signal by an electronic system. The detector unit converts the measured X-ray signals into digital signals and transmits the digital signals to a computer for processing. The computer analyzes and reconstructs the received signal data to generate a tomographic image, thereby providing detailed information on the internal structure of the scanned object.

In order to ensure that the CT equipment can normally operate, the CT machine detector unit of the CT machine detector needs to be disassembled, assembled and maintained regularly so as to ensure the scanning precision of the CT equipment and prolong the service life of the CT equipment. However, since many transition mating parts exist in the CT machine detector, they are different in shape and size, increasing the complexity of disassembly, and due to factors such as part size and misalignment, a certain insertion or disassembly force needs to be given to properly connect or disconnect the connected transition mating parts.
