Three-dimensional X-ray micro-velocimetry
A direct measurement of three-dimensional X-ray velocimetry with micrometer spatial resolution is presented. The key to this development is the use of a Laue crystal as an X-ray beam splitter and mirror. Three-dimensional flow velocities in a 0.4 mm-diameter tubing were recorded, with <5 µm spatial resolution and speeds of 0.7 mm s(-1). This development paves the way for three-dimensional veloc...
متن کاملImaging lung tissue oscillations using high-speed X-ray velocimetry.
This work utilized synchrotron imaging to achieve a regional assessment of the lung's response to imparted oscillations. The forced oscillation technique is increasingly being used in clinical and research settings for the measurement of lung function. During the forced oscillation technique, pressure oscillations are imparted to the lungs via the subjects' airway opening and the response is me...
متن کاملX-ray tests of a Pixel Array Detector for coherent x-ray imaging at the Linac Coherent Light Source
Test results are presented of a pixel array detector (PAD) developed for x-ray imaging at the Stanford Linear Coherent Light Source (LCLS). The basic module of the PAD consists of two bump-bonded chips: a reverse-biased silicon diode chip of 185× 194 pixels, each of which is coupled by bump-bonds to a charge integrating CMOS ASIC with digitization in each pixel. The LCLS experiment requires a h...
متن کاملDevelopment of a Stationary Chest Tomosynthesis System Using Carbon Nanotube X-ray Source Array
Jing Shan: Development of a stationary chest tomosynthesis system using carbon nanotube x-ray source array (Under the direction of Otto Zhou) X-ray imaging system has shown its usefulness for providing quick and easy access of imaging in both clinic settings and emergency situations. It greatly improves the workflow in hospitals. However, the conventional radiography systems, lacks 3D informati...
متن کاملHigh Repetition Rate X-ray Preionization Source
discharges. These photons can be generated by stopping 7OkeV electrons by a target made of high z material like tungsten or tantalum. In this contribution we describe the performance of an X-ray generator employing a corona plasma cathode [1]. Electrons can easily be extracted from a plasma on the surface of a dielectric. The plasma is generated by accelerating electrons, emitted from sharp edg...
