  • Patent number: 10732132
    Abstract: [PROBLEM TO BE SOLVED] To provide a radiation phase contrast imaging device having a small device configuration [SOLVING MEANS] The present invention focused on the findings that the distance between the phase grating 5 and the FPD 4 does not need to be the Talbot distance. The distance between the phase grating 5 and the FPD 4 can be more freely set. However, a self-image cannot be detected unless the self-image is sufficiently magnified with respect to the phase grating 5. The degree on how much the self-image is magnified on the FPD 4 with respect to the original phase grating 5 is determined by a magnification ratio X2/X1. Therefore, in the present invention, the magnification ratio is set to be the same as the magnification ratio in a conventional configuration. With this, even if the distance X2 between the radiation source 3 and the FPD 4 is reduced, a situation in which the self-image cannot be detected by the FPD 4 due to the excessively small size thereof does not occur.
