Claim:
1. A radiation inspecting apparatus having a radiation source emitting X-ray radiation to an inspection object, a radiation detector detecting X-ray radiation passing through the inspection object to capture projection images, and a stage disposed between the radiation source and the radiation detector for supporting the inspection object placed thereon, the stage being held movably in a substantially linear direction relative to guiding units, the radiation inspecting apparatus comprising: a stage drive unit transmitting driving power to the stage for moving the stage; a position detecting sensor detecting a position of the stage; a rotational fluctuation amount calculating unit calculating a rotational fluctuation amount of the stage representing inclination of the stage relative to the guiding units in accordance with detected positional information from the position detecting sensor upon imaging of the inspection object; a stage shift amount calculating unit calculating a stage shift amount in accordance with the rotational fluctuation amount; and an image reconstructing unit correcting a positional deviation of the stage in accordance with the stage shift amount and reconstructing the images.
