Abstract
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.
Claims12
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.
