Abstract:
1. An X-ray diagnosis apparatus, comprising: an X-ray source; an X-ray detector positioned in relation to the X-ray source and including a plurality of X-ray detection elements arranged in a first direction and a second direction, said plurality of X-ray detection elements configured convert detected X-rays to electric charges; a controller operably connected to the X-ray detector and configured to establish a setable imaging area within a first area of the X-ray detector; a controller input unit operably connected to the controller; a readout unit connected to the X-ray detector and configured to read out an electric charge from an X-ray detection element from a second area of the X-ray detector which is outside of the first area before reading out an electric charge from a detection element from the setable imaging area; a signal converter connected to the readout unit and configured to convert the electric charge read out from the X-ray detection element from the setable imaging area to X-ray image data; a display unit connected to the signal converter and configured to display the X-ray image data; and an amplifier connecting the read out unit to the signal converter, said amplifier configured to cut the electric charge read out from the X-ray detection element from the second area and to amplify the electric charge read out from the X-ray detection element from the setable imaging area.
