Paper Abstract

In high speed x-ray cineradiography, recording individual image frames separately is as important as generating successive flash x-ray pulses. Some researchers resolved the problem by employing multiple pairs of source-camera configuration. In this arrangement each pair of source and camera produces one separate image. So fast decaying image intensifying screens must be used to avoid the overlaps of the images exposed by different sources. Fast decaying screens, however, are not either easily available commercially, nor manufacturable at laboratory. This study proposes a cineradiographic technique which utilizes a conventional long decaying high speed image intensifying screen. The images exposed successively on the screen by multiple flash x-ray sources are sequentially recorded by multiple single frame MCP cameras. The first frame is singly exposed, the second doubly, and so on. The multi-exposed images are reconstructed to a singly exposed one by subtracting the images in the previous frame which contains one less image. Static test results with two-channel configuration revealed that the maximum frame rate of 105 fps could be attainable for shadow radiography.
