Analysing rapid internal movement in animals requires high-speed X-ray imaging to visualise motion of bony and soft body structures. The frame rate of X-ray cinematic camera is limited to 200 frames s(-1) with a shutter speed of 1/3000s, due to the low X-ray kV, required for small animals. These rates are often too slow for analysing the rapid accelerations of which small animals are capable. Here, we present three alternative digital-video systems that can be combined with a conventional X-ray intensifier to yield excellent slow-motion images of internal body parts of small animals. Each system shows high performance for different requirements of radiographic motion analysis.
