    • An X-ray imaging apparatus acquiring a differential phase contrast image of a test object without using a light-shielding mask for X-ray. The apparatus includes an X-ray source, a splitting element configured to spatially divide an X-ray emitted from an X-ray source and a scintillator configured to emit light when a divided X-ray beam divided at the splitting element is incident on the scintillator. The apparatus also includes a light-transmission limiting unit configured to limit transmitting amount of the light emitted from the scintillator and a plurality of light detectors each configured to detect the amount of light that has transmitted through the light-transmission limiting unit. The light-transmission limiting unit is configured such that a light intensity detected at each of the light detectors changes in response to a change in an incident position of the X-ray beam.
    • 一种X射线成像装置,在不使用用于X射线的遮光掩模的情况下获取被测物体的差分相位差图像。 该装置包括X射线源,分配元件,被配置为空间上划分从X射线源发射的X射线;以及闪烁器,其被配置为当分裂元件分割的分割的X射线束入射到所述X射线源时发光 闪烁体。 该装置还包括:光限制单元,被配置为限制从闪烁体发射的光的发射量;以及多个光检测器,每个光检测器被配置为检测透射通过光传输限制单元的光量。 光传输限制单元被配置为使得在每个光检测器处检测到的光强度响应于X射线束的入射位置的变化而变化。
