Abstract

The invention discloses a computer tomographic scanning imaging device, which comprises a variable dose CT scanning module used for adjusting the tube voltage of the X ray source in real time according to changes of effective thickness of an object to be detected in the X ray transillumination direction in the scanning process, implementing the circular locus X-CT scanning to the object to be detected according to the adjusted tube voltage of the X ray source, and sending the scanned projection images to a CT reconstruction module; and the CT reconstruction module is used for reconstructing CT according to the received projection images so as to obtain tomographic images of the object to be detected. The invention meanwhile discloses a computer tomographic scanning imaging method. The device and method of the invention are applicable to objects under detection with any complex structure, and will not be influenced by changes of effective thickness of the object to be detected in X ray transillumination direction.

Description

A computerized tomography imaging device and method technical field The present invention relates to computerized tomography (CT, Computed Tomography) technology, in particular to a CT scanning imaging device and method. Background technique CT technology is a new imaging technology that combines radiology and computer science. It aims to obtain projection data from external detection equipment through a certain ray source, such as an X-ray source, without damaging the internal structure of the object to be detected, and use a certain mathematical model and reconstruction imaging technology to generate the object to be detected using a computer. A 2D or 3D image of the interior of an object to reproduce the features inside the object to be inspected. In the existing CT technology, usually the object to be detected can only be scanned under the tube voltage of a certain fixed X-ray source. However, for the object to be detected whose effective thickness change rate is re...
