Abstract
Provided are an X-ray detector, a method, performed by the X-ray detector, of variably adjusting a window time of the X-ray detector, and an X-ray imaging device including the X-ray detector. The X-ray detector according to an embodiment of the present disclosure may obtain information about an X-ray emission end time point based on an X-ray emission end signal received from an automatic exposure control (AEC) device or a setting value for an X-ray emission time received from a workstation, adjust a window time based on the information about the X-ray emission end time point, and in response to the window time being ended, obtain X-ray image data by performing a readout.

A method of operating an X-ray detector, the method comprising:
- obtaining information about an X-ray emission end time point based on an X-ray emission end signal received from an automatic exposure control (AEC) device or a setting value for an X-ray emission time received from a workstation;
- adjusting a window time for the X-ray detector to receive X-rays that have passed through an object, based on the information about the X-ray emission end time point and information about a delay time due to a high-voltage generator (HVG) and the X-ray detector;
- and
- in response to the window time being ended, obtaining X-ray image data by performing a readout,
- wherein the delay time comprises at least one of a first delay time required for remaining X-rays in an X-ray tube in the HVG to dissipate after receiving the X-ray emission end signal, a second delay time required for afterglow of a scintillator in the X-ray detector to dissipate, and a third delay time required for electron-hole pairs to form and change a potential.
An X-ray detector comprising:
- an X-ray receiver configured to detect X-rays that have passed through an object, and converting the detected X-rays into electric signals;
- a communication interface comprising communication circuitry configured to perform data communication with an automatic exposure control (AEC) device, a high-voltage generator (HVG), or a workstation;
- a memory storing at least one instruction;
- and
- at least one processor, comprising processing circuitry, individually and/or collectively, configured to execute the at least one instruction stored in the memory,
- wherein at least one processor is configured to:
- obtain information about an X-ray emission end time point based on an X-ray emission end signal received from the AEC device through the communication interface, or a setting value for an X-ray emission time received from the workstation;
- adjust a window time for the X-ray detector to receive X-rays that have passed through the object, based on the information about the X-ray emission end time point and information about a delay time due to a high-voltage generator (HVG) and the X-ray detector;
- and
- in response to the window time being ended, obtain X-ray image data by performing a readout,
- wherein the delay time comprises at least one of a first delay time required for remaining X-rays in an X-ray tube in the HVG to dissipate after receiving the X-ray emission end signal, a second delay time required for afterglow of a scintillator in the X-ray detector to dissipate, and a third delay time required for electron-hole pairs to form and change a potential.
A computer program product comprising a non-transitory computer-readable storage medium having recorded thereon instructions for performing an operation method of an X-ray detector, the operation method comprising:
- obtaining information about an X-ray emission end time point based on an X-ray emission end signal received from an automatic exposure control (AEC) device or a setting value for an X-ray emission time received from a workstation;
- adjusting a window time for the X-ray detector to receive X-rays that have passed through an object, based on the information about the X-ray emission end time point and information about a delay time due to a high-voltage generator (HVG) and the X-ray detector;
- and
- in response to the window time being ended, obtaining X-ray image data by performing a readout,
- wherein the delay time comprises at least one of a first delay time required for remaining X-rays in an X-ray tube in the HVG to dissipate after receiving the X-ray emission end signal, a second delay time required for afterglow of a scintillator in the X-ray detector to dissipate, and a third delay time required for electron-hole pairs to form and change a potential.
