Problems solved by technology

[0002] At present, the existing X-ray system uses a single ray source. In order to achieve the required field of view and avoid geometric distortion of imaging, the X-ray source needs to keep a certain distance from the object under test and the flat panel detector. The distance between the ray source and the object under test is relatively large The imaging effect has a great impact

Abstract

The invention provides an X-ray imaging system based on a flat plate X-ray source array and a scanning imaging method. The X-ray imaging system comprises a flat plate detector and the X-ray source array. A spacer area is arranged between the flat plate detector and the X-ray source array, the spacer area is used for placing a measured object, the X-ray source array is an array composed of a plurality of X-ray sources, and spacing of each X-ray source is set between 1-20 mm. When image imaging of the measured object is required to be carried out, the X-ray sources in the X-ray source array areopened one by one or in groups, then local X-ray images corresponding to a radiated object can be formed on the flat plate detector, and a complete image of the radiated object can be generated by using image processing software to process and splice the local images generated by each X-ray source.

Description

technical field [0001] The invention relates to the technical field of X-ray detection, in particular to an X-ray imaging system and a scanning imaging method based on a flat-panel X-ray source array. Background technique [0002] At present, the existing X-ray system uses a single ray source. In order to achieve the required field of view and avoid geometric distortion of imaging, the X-ray source needs to keep a certain distance from the object under test and the flat panel detector. The distance between the ray source and the object under test is relatively large Imaging effects have had a huge impact. Contents of the invention [0003] The invention provides an X-ray imaging system and a scanning imaging method based on a flat-panel X-ray source array. [0004] The present invention provides an X-ray imaging system based on a flat-panel X-ray source array, comprising a flat-panel detector and an X-ray source array, a spacer is provided between the flat-panel detector ...
