Direct imaging of glymphatic transport using H217O MRI

open access: yesJCI Insight, 2021
The recently proposed glymphatic pathway for solute transport and waste clearance from the brain has been the focus of intense debate. By exploiting an isotopically enriched MRI tracer, H217O, we directly imaged glymphatic water transport in the rat ...

Vessel territory mapping after cerebral revascularization surgery using selective angiographic flat detector perfusion imaging [PDF]

open access: yesJournal of Integrative Neuroscience, 2021
The technical feasibility and diagnostic potential of angiographic flat-detector perfusion imaging technique, combining digital subtraction angiography with a flat-detector computed tomography steady-state perfusion imaging, was explored in patients ...

Directional interpolation of noisy images [PDF]

open access: yes2008 15th IEEE International Conference on Image Processing, 2008
Most of the existing image interpolation schemes assume that the image is noise free. This assumption is invalid in practice because noise will be corrupted in the image acquisition process. The conventional way is to denoise the image first and then interpolate the denoised image.

Achieving single nucleotide sensitivity in direct hybridization genome imaging

open access: yesNature Communications, 2022
Visualisation of point mutations in situ is informative for studying genetic diseases. Here the authors report single guide genome oligopaint via local denaturation fluorescence in situ hybridisation, sgGOLDFISH, a direct hybridisation genome imaging ...

Direct Noise-Resistant Edge Detection with Edge-Sensitive Single-Pixel Imaging Modulation

open access: yesIntelligent Computing, 2023
The majority of edge detection methods are applied after the capture of object photos. Thus, edge detection quality suffers when disturbances occur during imaging. This work proposes an effective edge detection technique for single-pixel imaging (SI).

Imaging of intranasal drug delivery to the brain

open access: yes, 2020
Intranasal (IN) delivery is a rapidly developing area for therapies with great potential for the treatment of central nervous system (CNS) diseases. Moreover, in vivo imaging is becoming an important part of therapy assessment, both clinically in humans ...

Near-Field 3D Sparse SAR Direct Imaging with Irregular Samples

open access: yesRemote Sensing, 2022
Sparse imaging is widely used in synthetic aperture radar (SAR) imaging. Compared with the traditional matched filtering (MF) methods, sparse SAR imaging can directly image the scattered points of a target and effectively reduce the sidelobes and clutter

High-Contrast Imaging: Hide and Seek with Exoplanets

open access: yesGalaxies
So far, most of the about 5700 exoplanets have been discovered mainly with radial velocity and transit methods. These techniques are sensitive to planets in close orbits, not being able to probearge star–planet separations.
