Abstract

The invention discloses CT (computed tomography) equipment and a usage method thereof. The CT equipment comprises an electron beam generating device, an annular reflection target and an annular detector array, wherein the electron beam generating device comprises an electron gun, deflection scanning devices and a current-limiting device; the electron gun generates electron beams; the deflection scanning devices deflect the electron beams, and the deflection directions are changed along with time to realize annular scanning; the current-limiting device is provided with a plurality of holes arranged annularly; when the electron beams carry out scanning along the holes arranged annularly, a plurality of electron beams distributed annularly are output; the annular reflection target and the annularly-distributed electron beams are coaxially arranged; the electron beams bombard the annular reflection target to generate X rays intersecting with the axes of the electron beams distributed annularly; the annular detector array is coaxially arranged with the annular reflection target and comprises a plurality of detector units; and the X rays enter the corresponding detector units after penetrating through a detected 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...
