Embodiment Construction

[0011] see figure 1 , single radiation source dual imaging scanning radiation imaging method, it uses radiation source 1 to emit two X-rays with different angles. Each X-ray beam passes through the container under test and is respectively received by the detector A3 and the detector B4, and then converted into an electrical signal and input to the corresponding image acquisition module A5 and image acquisition module B6 respectively. The image signal is input to the computer monitor A7 by the image acquisition module A5 to display the measured image. The image signal is input by the image acquisition module B6 into the computer display B8 or in different windows of the same computer display A7 to display the measured image simultaneously.

[0012] see figure 2 , a device for realizing a single radiation source dual imaging scanning radiation imaging method. It includes a radiation source 1, two detector arrays 3 and 4 and an image acquisition system connected to each detec...

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...
