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

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 ...

Gradient amplifier imperfections in NMR imaging

open access: yes, 1992
This paper describes the influence of the transition distortion of gradient amplifiers on direct Fourier NMR imaging techniques. We demonstrate artifacts arising in the real measurement of the spin density images.

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.

Mid-infrared gas imaging with direct absorption spectroscopy

open access: yes, 2023
Methane leaks down to 0.25 ml/min can be located and quantified by a single concentration image with a resolution of few ppm*m using direct absorption spectroscopy in combination with mid-infrared imaging and image processing ...
