Abstract
A phase contrast radiation imaging apparatus is includes a radiation source, a diffraction grating, and a radiation image detector. The radiation image detector is equipped with a charge generating layer that generates electric charges when irradiated with radiation, and charge collecting electrodes that collect the electric charges. The charge collecting electrodes are linear electrode groups, constituted by linear electrodes which are arranged at a constant period and are electrically connected to each other, provided to have different phases from each other. Thereby, use of a conventional amplitude diffraction grating is obviated.
