Abstract
Provided are an X-ray detector automatically correcting an automatic exposure control (AEC) sensing area, based on an image obtained using an AEC sensor array, and a method of operating the X-ray detector. The X-ray detector may detect, using an AEC sensor array, X-rays that have passed through an object, obtain a one-dimensional (1D) image by quantifying a dose of the detected X-rays into a signal value, identify a symmetric point from the 1D image, based on a signal value for each pixel of the 1D image, and adjust respective locations of a plurality of AEC sensing areas so that the plurality of AEC sensing areas are symmetrical to each other with respect to the identified symmetric point.
Claims15
An X-ray detector comprising:
- a plurality of photodetection elements including a plurality of pixels and configured to detect X-rays;
- an automatic exposure control (AEC) sensor array including at least one AEC sensor configured to detect X-rays that have passed through an object and to quantify a dose of the detected X-rays as a signal value and output the signal value;
- a memory storing one or more instructions;
- and
- at least one processor, comprising processing circuitry, configured to execute the one or more instructions stored in the memory,
- wherein at least one processor, individually and/or collectively, is configured to:
- obtain a one-dimensional (1D) image, based on the signal value output by the AEC sensor array,
- identify a symmetric point from the 1D image, based on a signal value for each pixel of the 1D image, and
- adjust respective locations of a plurality of AEC sensing areas so that the plurality of AEC sensing areas are symmetrical to each other with respect to the identified symmetric point.
A method of operating an X-ray detector including an automatic exposure control (AEC) sensor, the method comprising:
- detecting, using an AEC sensor array, X-rays that have passed through an object, and obtaining a one-dimensional (1D) image by quantifying a dose of the detected X-rays into a signal value;
- identifying a symmetric point from the 1D image, based on a signal value for each pixel of the 1D image;
- and
- adjusting respective locations of a plurality of AEC sensing areas so that the plurality of AEC sensing areas are symmetrical to each other with respect to the identified symmetric point.
A computer program product including a non-transitory computer-readable storage medium storing instructions readable by an X-ray detector including an automatic exposure control (AEC) sensor, the instructions, when executed by at least one processor, individually and/or collectively, of the X-ray detector, cause the X-ray detector to perform operations including:
- detecting, using an AEC sensor array, X-rays that have passed through an object, and obtaining a one-dimensional (1D) image by quantifying a dose of the detected X-rays into a signal value;
- identifying a symmetric point from the 1D image, based on a signal value for each pixel of the 1D image;
- and
- adjusting respective locations of a plurality of AEC sensing areas so that the plurality of AEC sensing areas are symmetrical to each other with respect to the identified symmetric point.
