1. An X-ray radioscope, comprising:
an X-ray source that radially emits X-rays;
a sample holder that holds a sample, the sample holder placed in front of the X-ray source in order for the sample to be irradiated by X-rays emitted from the X-ray source;
a planar charge coupled device (CCD) including CCDs planarly arranged, the planar CCD being placed away from the sample holder to detect X-rays transmitted through the sample such that the planar CCD obtains an X-ray transmission image of the sample; and
a movement unit that moves the planar CCD and the sample holder relative to each other in synchronization with obtaining the X-ray transmission image by the planar CCD,
wherein the planar CCD has 500 or more pixels along a movement direction relative to the sample, and
wherein the planar CCD is arranged so that in relative movement of the sample holder and the planar CCD, imaging ranges are adjacent to each other in a direction perpendicular to the relative movement direction of the sample and a central axis of the X-ray, and
the X-ray radioscope further comprises two or more planar CCDs with different charge transfer directions from each other.
