Abstract:
A radiation image data obtaining method for obtaining an image signal representing radiation image information from a solid-state radiation detector having a capacitor for storing an electric charge in accordance with a dose of radiation irradiated thereon and a stripe electrode comprising a plurality of linear electrodes disposed on the capacitor, the solid-state radiation detector having an area insensitive to the radiation, the insensitive area corresponding to a portion of the stripe electrode in the longitudinal direction thereof,the radiation image data obtaining method comprising the step of carrying out, for each linear electrode and in the longitudinal direction of the stripe electrode, correction of a component of the image signal corresponding to an area other than the insensitive area so that a dark current component included in the image signal is reduced based on a component of the image signal corresponding to the insensitive area.
