X-ray diagnosis apparatus
View Patent ↗An X-ray diagnosis apparatus including an X-ray detector which has a plurality of detection elements. On the X-ray detector, there is a first area and a second area. A readout unit reads out an electric charge from a detection element on the first area before reading out the electric charge from a detection element on the second area. A display unit displays an X-ray image data which is created by the electric charge read out from the detection element on the second area.
