| 摘要 |
The invention relates to a phase-contrast x-ray imaging device (2), in particular for the medical field, comprising an x-radiation source (6) for generating an x-radiation field and an x-ray detector (8) having a one-dimensional or two-dimensional arrangement of pixels (10), wherein a phase-contrast differential amplifier (14) is positioned between the x-radiation source (6) and the x-ray detector (10), by means of which phase-contrast differential amplifier spatial phase differences in the x-radiation field are amplified during operation. |
