Radiation imaging method and device with single radiation source and dual scans

Abstract

A dual-image scan radiation imaging method using single radiation source and its equipment is disclosed. A single radiation source is used to emit two X-ray beams. Two detector arrays and two image acquiring systems connected to the said arrays are used to obtain two scanned images. The image acquiried by the first detector array is the front view of object. The image acquired by the second detector array is the side view of object. Its advantages include simple structure, and high test speed.

Description

technical field [0001] The invention relates to a scanning radiation imaging method and a device thereof for a radiation detection system of a large object, in particular to a scanning radiation imaging method and a device used in a large container radiation inspection system. Background technique [0002] With the help of the penetrating ability of high-energy X-rays, radiation imaging technology can see through the interior of an object without contact, so as to obtain a perspective image of the object. In the prior art, for the inspection of large objects, the working principle of scanning radiation imaging is that the radiation source emits X-rays, and the X-rays pass through the measured object and are received by the detector and then converted into electrical signals and input to the image acquisition module. The module inputs the image signal into the computer monitor to display the measured image. In general, the perspective image formed by radiation imaging is the...

Problems solved by technology

In order to solve this problem, in the field of radiation imaging, computed tomography technology is a relatively mature subject reconstruction technology, but the disadvantages of using this technology are: not only the complex coefficient is large, the cost is high, but also it is impossible to quickly perform large-scale object reconstruction. to check
