Direct high-resolution X-ray imaging exploiting pseudorandomness
Light: Science & Applications, 2023 High-resolution X-ray sample field image is directly retrieved in a single shot using the mathematical relations of spatially pseudorandom (i.e., speckle) fields.

Direct imaging of APP proteolysis in living cells [PDF]
PeerJ, 2017 Alzheimer’s disease is a multifactorial disorder caused by the interaction of genetic, epigenetic and environmental factors. The formation of cytotoxic oligomers consisting of Aβ peptide is widely accepted as being one of the main key events triggering ...

Direct imaging of exoplanets [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 Most of the exoplanets known today have been discovered by indirect techniques, based on the study of the host star radial velocity or photometric temporal variations. These detections allowed the study of the planet populations in the first 5–8 AU from the central stars and have provided precious information on the way planets form and evolve at such ...

PET imaging of neurotransmission using direct parametric reconstruction
NeuroImage, 2020 Receptor ligand-based dynamic Positron Emission Tomography (PET) permits the measurement of neurotransmitter release in the human brain. For single-scan paradigms, the conventional method of estimating changes in neurotransmitter levels relies on fitting

Stereotactic Injection of DTI-015 into Recurrent Malignant Gliomas: Phase I/II Trial
Neoplasia: An International Journal for Oncology Research, 2003 DTI-015 (BCNU in 100% ethanol) utilizes solvent facilitated perfusion for the intratumoral treatment of gliomas. The ethanol solvent vehicle facilitates a rapid and thorough saturation of the tumor with the dissolved anticancer agent BCNU. We conducted a

Direct Imaging of Functional Networks [PDF]
Brain Connectivity, 2014 In blood-oxygenation-level-dependent functional magnetic resonance imaging (fMRI), current methods typically acquire ∼500,000 imaging voxels at each time point, and then use computer algorithms to reduce this data to the coefficients of a few hundred parcels or networks.

Image Denoising with Directional Bases [PDF]
2007 IEEE International Conference on Image Processing, 2007 Directional information is an important component of both natural and synthetic images, and it is exploited in many image processing applications. Directional basis analysis is used to capture significant structural information. This paper presents an empirical study of image denoising with directional bases. We consider two distinct approaches.
