Objective. The noise characteristics of digital x-ray imaging devices are determined by
contributions such as photon noise, electronic noise, and fixed pattern noise, and can be …

Purpose Accurately and precisely estimating the noise power spectrum (NPS) is important
for characterizing the performance of a radiography detector and helpful for improving the …

Most traditional infrared and visible image fusion methods often ignore noise in acquisition
or transmission and their performance inevitably decreases in practical applications. To …

Purpose: The fixed pattern noise in radiography image detectors is caused by various
sources. Multiple readout circuits with gate drivers and charge amplifiers are used to …

In fluoroscopic imaging, we can acquire x-ray image sequences using a flat-panel dynamic
radiography detector. Because of the charge trapping at photodiodes, lag signals occur at …

Lag signal problems occur in acquiring X-ray image sequences from dynamic flat-panel
detectors due to amorphous pixel photodiodes and incomplete readouts. Based on a linear …

Noise power spectrum (NPS) at zero frequency can efficiently represent noise properties of
imaging systems. However, estimations of zero-frequency NPS are susceptible to distortion …

Lag signals occur at images sequentially acquired from a flat-panel (FP) dynamic detector in
fluoroscopic imaging due to charge trapping in photodiodes and incomplete readouts. This …

Objective: In this paper, a novel dual-layer detector is considered to acquire X-ray images of
high signal-to-noise ratio (SNR) as well as detective quantum efficiency (DQE) especially for …

For fluoroscopic imaging, flat-panel dynamic detectors can acquire X-ray image sequences
with frame rates higher than 300 frames per second. However, the sequentially acquired …
