Samsung patents X-ray detector that adjusts timing to reduce image noise

This patent describes an X-ray detector that automatically adjusts its data collection window based on when the X-ray beam stops. It accounts for delays in the equipment, such as residual radiation and sensor afterglow, to ensure it only reads clear image data.

Why it mattersThis could lead to sharper medical images with less noise, helping doctors see details more clearly during scans.

In the filing’s own words

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.

What exactly they claim (claim 1)

1. 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.
