Screen-printed flexible MRI receive coils. [PDF]
, 2016 Magnetic resonance imaging is an inherently signal-to-noise-starved technique that limits the spatial resolution, diagnostic image quality and results in typically long acquisition times that are prone to motion artefacts.

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Evaluation of image Signal-to-Noise Ratio in Time-of-Flight PET [PDF]
2011 IEEE Nuclear Science Symposium Conference Record, 2011 In PET imaging Noise Equivalent Counts (NEC) is a common image quality index, derived to be proportional to image SNR2 and used as an index of general system performance. Many studies have shown that TOF information leads to reduced noise, faster image convergence, and improved SNR.

Signal-to-noise properties of correlation plenoptic imaging with chaotic light
, 2019 Correlation Plenoptic Imaging (CPI) is a novel imaging technique, that exploits the correlations between the intensity fluctuations of light to perform the typical tasks of plenoptic imaging (namely, refocusing out-of-focus parts of the scene, extending ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
