X-ray detector of a grid-based phase-contrast X-ray device and method for operating a grid-based phase-contrast X-ray device

摘要

The invention relates to an X-ray detector of a grid-based phase-contrast X-ray device and to a method for operating a grid-based phase-contrast X-ray device. Signal values from detector elements (3) are combined into group signal values (6). From the group signal values (6), an image-calculating unit calculates an X-ray phase value.
