ct system and its detection device

Abstract

The present invention provides a detection device, comprising: a housing assembly having an accommodating chamber, and an incident window communicated with the accommodating chamber; a detection chip arranged in the accommodating chamber for detecting The rays passing through the incident window output electrical signals; the signal processing board is arranged in the accommodating chamber, the signal processing board is electrically connected to the detection chip, and is used to receive and process the output of the detection chip an electric signal; and a separation component, which is arranged on the housing component, and the signal processing board and the detection core are respectively located on two sides of the separation component. The separation part can separate the heat generated by the detection chip from the heat generated by the signal processing board on the shell assembly, reducing the coupling between heat sources, thereby ensuring that the temperature of the detection chip and the signal processing board will not rise, and ensuring that the detection device can Normal response, thereby ensuring the correction stability of the detection device and improving the image quality. The invention also provides a CT system.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a CT system and a detection device thereof. Background technique [0002] At present, imaging equipment such as a CT machine usually emits X-rays to scan the human body through a ball tube, and receives and detects the X-rays through a detector. The focus position of the tube will shift during the scanning process, but if the original focus position data of the tube is still used in image reconstruction, it will cause image artifacts, which is not conducive to the doctor's diagnosis. Therefore, it is necessary to refer to the position of the tube focus by the detector. The position is detected, and after detection, the detector receives X-ray imaging, and the X-ray received by the detector is corrected by the reference detector to perform image imaging to ensure image quality. However, the superposition of heat generated by the reference detector during operation affec...
