Toward-1mm depth precision with a solid state full-field range imaging system [PDF]

open access: yes, 2006
Previously, we demonstrated a novel heterodyne based solid-state full-field range-finding imaging system. This system is comprised of modulated LED illumination, a modulated image intensifier, and a digital video camera. A 10 MHz drive is provided with 1

A Microwave Polarimeter Demonstrator for Astronomy with Near-Infra-Red Up-Conversion for Optical Correlation and Detection

open access: yesSensors, 2019
This paper presents a 10 to 20 GHz bandwidth microwave polarimeter demonstrator, based on the implementation of a near-infra-red frequency up-conversion stage that allows both the optical correlation, when operating as a synthesized-image interferometer,

Millimeter-Wave Imaging System Based on Direct-Conversion Focal-Plane Array Receiver

open access: yesSensors, 2022
A new approach to millimeter-wave imaging was suggested and experimentally studied. This approach can be considered as the evolution of the well-established focal-plane array (FPA) millimeter-wave imaging.

PET imaging of neurotransmission using direct parametric reconstruction

open access: yesNeuroImage, 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

open access: yesNeoplasia: 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 exoplanets [PDF]

open access: yesPhilosophical 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 ...

Direct Imaging of Functional Networks [PDF]

open access: yesBrain 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]

open access: yes2007 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.
