Abstract
An X-ray detector integral with an automatic exposure control (AEC) device can include an X-ray detection part configured to detect X-rays irradiated from an X-ray source and generate X-ray image data; and an automatic exposure detection board located below the X-ray detection part and configured to generate an X-ray sensing signal for automatic exposure control based on residual X-rays which have passed by or through the X-ray detection part.

An X-ray detector integral with an automatic exposure control (AEC) device, the X-ray detector comprising:
- an X-ray detection part configured to detect X-rays irradiated from an X-ray source and generate X-ray image data;
- and
- an automatic exposure detection board located below the X-ray detection part and configured to generate an X-ray sensing signal for automatic exposure control based on residual X-rays which have passed by or through the X-ray detection part,
- wherein the X-ray detector further comprises:
- an electromagnetic wave absorption sheet configured to absorb energy from the X-rays for protecting components within the X-ray detector;
- a scattering prevention sheet configured to prevent backscattering of the X-rays;
- and
- a driving circuit fixing plate configured to fix a driving circuit of at least one X-ray sensor and the automatic exposure detection board,
- wherein the electromagnetic wave absorption sheet, the scattering prevention sheet and the driving circuit fixing plate are disposed between the at least one X-ray sensor and the automatic exposure detection board.
A device for facilitating automatic exposure control (AEC), the device comprising:
- at least one X-ray sensor configured to detect X-rays irradiated from an X-ray source for generating X-ray image data of a body part of a patient;
- and
- an automatic exposure detector configured to generate an X-ray sensing signal for automatic exposure control of the X-ray source based on residual X-rays from the X-rays which have passed by or through the at least one X-ray sensor,
- wherein the device further comprises:
- an electromagnetic wave absorption sheet configured to absorb energy from the X-rays for protecting components within the device;
- a scattering prevention sheet configured to prevent backscattering of the X-rays;
