摘要：

X-ray imaging with a high spatial resolution is essential for observing small features inside an object. We examined a new parallel X-ray imaging system to improve the spatial resolution of a conventional projection-type X-ray imaging system. Parallel X-rays were obtained by using a polycapillary optic, which had a parabolic shape, combined with an X-ray tube. The field of view of the imaging system was limited by the diameter of the polycapillary optic. In the proposed parallel X-ray imaging system, a spatial resolution of 12 lp/mm was achieved. The parallel X-ray imaging system is expected to be useful for examining a small field with high spatial resolution.
