Abstract

A CT device and a CT imaging method thereof. The CT device comprises: an annular electron gun array (7) that comprises multiple electron guns, wherein each electron gun is configured to emit an electron beam sequentially along a radial direction of the annular electron gun array (7) according to a predetermined pulse sequence; an accelerating cavity (8), which is arranged at an annular inner side of the annular electron gun array (7), comprises multiple concentric coaxial cavities that are embedded together, works in π mode and is used for sequentially accelerating the electron beam emitted by each electron gun of the annular electron gun array (7); an annular transmission target (9), which is arranged at an annular inner side of the accelerating cavity (8), and bombarded by the accelerated electron beam to generate an X-ray; and an annular detector (11), which receives the X-ray that penetrates an examined object.

Description

technical field [0001] The technology relates to medical imaging, industrial detection and other fields. It can be directly applied to medical applications that require ultra-high-speed imaging, and can also be used in industrial applications such as non-destructive testing. Background technique [0002] CT is the abbreviation of Computed Tomography, that is, computerized tomography technology, which is a scanning method that uses computer technology to reconstruct the tomographic image of the measured object to obtain a three-dimensional tomographic image. The scanning method is to penetrate the measured object through the rays of a single axis, and according to the different absorption and transmittance of each part of the measured object, the transmitted rays are collected by the computer and imaged through three-dimensional reconstruction. The CT mentioned in this patent refers to X-ray CT unless otherwise specified. [0003] According to the development, CT can be div...
