CT system and detection device thereof

Abstract

The invention provides a detection device which comprises a housing assembly, a detection chip, a signal processing plate and a separation part, wherein the housing assembly has an accommodation cavity and an entrance window which is communicated with the accommodation cavity; the detection chip is arranged in the accommodation cavity and used for detecting rays passing through the entrance windowand outputting electric signals; the signal processing plate is arranged in the accommodation cavity, electrically connected with the detection chip and used for receiving and processing the electricsignals output by the detection chip; the separation part is arranged on the housing assembly, and the separation part and the detection chip are located on the two sides of the separation part respectively. The separation part can separate the heat produced by the detection chip and the heat produced by the signal processing plate on the housing assembly, coupling between the heat sources is reduced, further the temperature of the detection chip and the signal processing plate is ensured not to rise, normal response of the detection device is ensured, the amendment stability of the detectiondevice is further guaranteed, and the image imaging quality is improved. The invention further 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...
