“Carestream is a leader in using AI for noise cancellation with X-ray images. Our team of imaging scientists has been able to separate image noise from sharpness and contrast using AI-based algorithms that result in remarkable image quality,” said Jill Hamman, Worldwide Marketing Manager, Glob...
image sensoractive pixelx-ray diffractionA new large area imager for X-ray crystallography is described based on active pixel sensor technology. In order to meet the demanding requirements for crystallography the detector is designed with real time correction for reset noise, nonlinearity, spatial ...
Effective noise removal technique for enhancement of the X-ray image / Azman MohamedEffective noise removal technique for enhancement of the X-ray image / Azman MohamedThe noise removal is an important aspect of image processing, because the human visual System is very sensitive to the high amplit...
Previously, an Al0.52In0.48P p+-i-n+ spectroscopic photon counting X-ray photodiode with 2μm thick i layer (200μm diameter) was shown to suffer from energy-dependent incomplete charge collection noise (Lioliou et al., 2019). Subsequent measurements on a larger (400μm diameter) Al0.52...
Furthermore, the correlation between absorption and dark-field image was calculated. CONCLUSIONS: These results provide the understanding of the noise characteristics of grating-based phase-contrast imaging and will help to improve image quality. 展开 关键词: noise x-ray phase-contrast imaging x-ray...
