High Resolution In-Vivo Electrode Localization Using Microfocal X-Rays
Neuroscientists lack the ability to perform in-vivo electrode localization with high accuracy, especially in deep brain structures. The design, implementation and testing of a microfocal x-ray stereo system that offers an efficient, accurate, and relatively low-cost solution this localization problem is presented. The results indicate the ability to localize a targets to within ~50 microns, in ...
متن کاملExamining nanoparticle assemblies using high spatial resolution x-ray microtomography
An experimental system has been designed to examine the assembly of nanoparticles in a variety of process engineering applications. These applications include the harvesting from solutions of nanoparticles into green parts, and the subsequent sintering into finished components. The system is based on an x-ray microtomography with a spatial resolution down to 5 mm. The theoretical limitations in...
متن کاملRecent progress of avalanche photodiodes in high-resolution X-rays and γ-rays detection
We have studied the performance of large area avalanche photodiodes (APDs) recently developed by Hamamatsu Photonics K.K, in high-resolution X-rays and γrays detections. We show that reach-through APD can be an excellent soft X-ray detector operating at room temperature or moderately cooled environment. We obtain the best energy resolution ever achieved with APDs, 6.4 % for 5.9 keV X-rays, and ...
متن کاملOptimal material discrimination using spectral x-ray imaging.
Spectral x-ray imaging using novel photon counting x-ray detectors (PCDs) with energy resolving abilities is capable of providing energy-selective images. PCDs have energy thresholds, enabling the classification of photons into multiple energy bins. The extra energy information provided may allow materials such as iodine and calcium, or water and fat to be distinguishable. The information conte...
متن کاملMassive Molecular Outflows at High Spatial Resolution
We present high-spatial resolution Plateau de Bure Interferometer CO(2–1) and SiO(2–1) observations of one intermediate-mass and one high-mass star-forming region. The intermediate-mass region IRAS 20293+3952 exhibits four molecular outflows, one being as collimated as the highly collimated jet-like out-flows observed in low-mass star formation sources. Furthermore, comparing the data with addi...
