Abstract

The invention discloses portable CT (computed tomography) scanning equipment, a portable CT system and a CT detection method. The equipment comprises a rotary table, a transmission module, a detection module, a driving module, an acquisition module and a power supply module, wherein the transmission module and the detection module are arranged on the rotary table oppositely; the driving module, the acquisition module and the power supply module are arranged on the rotary table; the transmission module, the detection module, the driving module, the acquisition module and the power supply module are detachably assembled on the rotary table; the driving module is used for driving the transmission module and the detection module on the rotary table to rotate; the transmission module is used for transmitting detection rays; the detection module is used for detecting the detection rays; the acquisition module is used for acquiring digital signals to re-establish CT images; the power supply module is used for providing electric power required by the CT scanning equipment. According to the invention, the CT scanning equipment is designed to be composed of at least one detachable component, so that the huge consumption of labor and resources caused by conveying huge CT scanning equipment to a test scene is omitted, and convenient and effective field CT detection service is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of non-destructive testing, and in particular to a portable CT scanning device, a portable CT system and a CT testing method. Background technique [0002] CT (Computed Tomography, computerized tomography) was first applied in the field of medical imaging, and then introduced into the field of industrial nondestructive testing. Due to its non-insertion and non-interference detection characteristics, CT has also been used in agriculture, forestry, geophysics, and chemical industry. great application. [0003] During the CT detection process, the emission source in the CT detection equipment will generate ionizing radiation such as X-rays or γ-rays. In practical applications, it is necessary to place the CT detection equipment in an electromagnetic shielding room or an electromagnetic shielding cavity to reduce the impact of ionizing radiation The testers and the influence of the surroun...
