Abstract

The invention discloses a high-energy sparse CT (computed tomography) detector, a CT detection system and a detection method, belongs to the technical field of CT detection, and solves the problems that a CT detection device in the prior art is high in cost, not beneficial to popularization and application of equipment, low in cost, incapable of ensuring imaging precision and the like. The CT detector comprises high-energy detectors and low-energy detectors, the high-energy detectors and the low-energy detectors are arranged in a back-to-back mode, and one low-energy detector is arranged aboveeach high-energy detector; the number of rows of the low-energy detectors is larger than the number of rows of the high-energy detectors, and at least part of the high-energy detectors are distributed in a centralized mode. Part of high-energy detectors of the CT detector are arranged in a centralized mode, the cost is reduced, and meanwhile the imaging precision is high.

Description

technical field [0001] The invention belongs to the technical field of CT detection, and in particular relates to a high-energy sparse CT detector, a CT detection system and a detection method. Background technique [0002] Among the X-ray-based explosives inspection technologies, X-ray computed tomography imaging technology (referred to as "CT technology") is highly valued in the field of security inspection due to its own unique advantages. The only EDS (Explosive Detection System) security inspection equipment certified by the Transportation Security Administration (TSA, Transportation Security Administration) in the United States is CT equipment, which shows the status of X-ray CT technology in the field of security inspection. [0003] X-ray CT security inspection technology is to reconstruct the CT data to obtain the tomographic image of the scanned object, and analyze the characteristic data in the tomographic image to realize the identification of dangerous items in ...
