Abstract
In a binocular steroscopic scanning radiographic imaging method, X-rays emitted by the same radiation source are used. The X-rays pass through a double-slit collimator to form two X-ray beam sectors, which are symmetric or asymmetric and have an angle between them. The X-ray beam sectors, after penetrating through an object under detection, are received by the left and right detector array, respectively, then converted into electric signals to be inputted to the respective image acquisition systems, and received by a computer processing system for image processing and displaying. A system corresponding to the method comprises a radiation source, a beam controller, two mutually connected arms of detector arrays, image acquisition systems connected respectively to each of the detector arrays and a computer processing system. The present invention can display the transmission images detected by each of the detector arrays as well as tomograms with different depth reconstructed from the transmission images according to the principle of parallax. The present invention is convenient, fast in detection and realizes with low cost the recognition of objects of different depths.
