| description | The Tsinghua University successfully invented a dual-projection digital radiography system, which adopts two 60Co radiation sources aiming at two patented high-pressure gas chamber array detectors respectively. The system can obtain both vertical and horizontal projections from one scan, providing more information for image examination. Comparing with traditional single-projection system, the dual-projection system adopts two 60Co radiation sources that are deployed on the side and at the bottom respectively, but the adoption of two radiation sources also brings problems like γ photon scatter and more complicated radiation information process, and image processing algorithms needs improving to obtain radiation images of better quality. To solve the above-mentioned problems, this paper presents a comprehensive radiation information processing method, including correcting the photon scatter between two radiation sources, designing and implementing a radiation information processing and analyzing platform, and improving radiation image processing algorithms. This work has been applied in the system at a nuclear facility access for over two years and proved to be reliable, achieving application innovation among similar-type systems. |
