Abstract: An X-ray imaging apparatus comprises a first grid, a second grid, and an X-ray image detector. The first grid passes X-rays emitted from an X-ray source and produces a first periodic pattern image. The second grid opposes the first grid. The second grid partly blocks the first periodic pattern image and produces a second periodic pattern image with moiré fringes. The X-ray image detector detects the second periodic pattern image and produces image data. The X-ray image detector has pixels arranged in two dimensions in X and Y directions. The M pixels arranged in the Y direction form one group. The group is shifted in the Y direction by the number of the pixels less than M each time. A phase of an intensity modulated signal, composed of pixel values of the pixels in the each shifted group, is calculated. Thereby a differential phase image is produced.

The grooves, formed between the X-ray transmitting sections, extend in Y direction and are arranged in X direction orthogonal to the Y direction. In the grooves, the supporting portions protrude from sides of the X-ray transmitting sections in the X direction and are arranged alternately in the Y direction. The supporting portions support the X-ray transmitting sections when the grooves are filled with an X-ray absorbing material through electroplating. The supporting portions prevent the X-ray transmitting sections from falling over due to waves of a plating liquid and uneven growth of the X-ray absorbing material.
