Abstract
X-ray imaging technologies such as digital radiography (DR), is an important aspect of modern non-destructive testing and medical diagnosis. Innovative flexible X-ray detector technologies have recently been proposed and are now receiving increasing attention owing to their superior material flexibility compared with traditional flat-panel detectors. This work aims to study these innovative flexible X-ray detectors in terms of their effectiveness in DR imaging, such as detection efficiency and spatial resolution. To achieve this goal, first, a Monte Carlo model was developed and calibrated to an in-lab 150 kV DR imaging system containing a flat-panel X-ray detector. Second, the validated model was updated with various types of flexible X-ray detectors to assess their performance in nearly realistic conditions. Key parameters such as the detection efficiency pertaining to the crystal material and thickness were studied and analyzed across a broader energy range up to 662 keV. Finally, the imaging performance of the different detectors was evaluated and compared to that of the flat-panel detector in the 150 kV DR imaging system. The results show that the flexible detectors such as the CsPbBr3 crystal detector deliver promising performance in X-ray imaging and can be applied to a wider range of application scenarios, especially those requiring accurate detection at challenging angles.
