Abstract
A direct-conversion X-ray detector according to an embodiment includes a plurality of anode electrodes, at least one cathode electrode, and electric-field forming circuitry. The anode electrodes are aligned in a cone angle direction of an incident X-ray. The cathode electrode is positioned on an incident side of an X-ray relative to the anode electrodes, and that opposes the anode electrodes. The electric-field forming circuitry configured to form an electric field in a direction based on a cone angle of the X-ray, between the anode electrodes and the cathode electrode.
