Development of X-ray Coherent Scatter Projection Imaging Systems
Coherent scatter x-ray imaging systems are sensitive to material structure and chemical composition, and generate images with contrast superior to conventional transmission x-ray imaging. The goal of this thesis was to develop a scatter projection imaging system capable of acquiring images in less …

Geophysical Imaging of Earth Processes: Electromagnetic Induction in Rough Geologic Media, and Back-Projection Imaging of Earthquake Aftershocks
… record the 12 days of the aftershocks. The backprojection imaging method is applied to the entire AIDA dataset to detect and locate aftershocks. The method takes advantage of staking of many seismograms and improves the signal-to-noise ratio for detection. The catalog obtained from the …

An account of silence in diagnostic radiography : a cultural quilt
… radiography (X-ray); collectively referred to as projection imaging. Because silence is multi-faceted and often ambiguous, requisite methods of collages and follow-up conversations were used in the study providing the flexibility to explore a fluid concept. Projection imaging staff consisting of …

3D Reconstruction of Tubular Structures Using MRI Projection Images
After imaging information became available in digital form, techniques for acquiring volumetric data evolved. 3D reconstruction is mostly performed using multislice stack images. The objective of this dissertation is to introduce a simple magnetic resonance technique for imaging tubular structures, …

X-ray phase contrast imaging of preclinical atherosclerosis
… biochemical profile, followed by angiographic imaging. However, patients with subclinical atherosclerotic disease can also be at high risk for ACS. In fact, nearly half of the patients suffer from sudden cardiac death without any prior indication of atherosclerotic disease. For these patients, …

BEYOND ARABIDOPSIS: UNRAVELLING THE HIDDEN WORLD OF CA2+ SIGNALLING ACROSS SPECIES VIA MULTISCALE IMAGING TECHNOLOGIES
… these processes both biological tools and imaging technologies have rapidly evolved. In particular, the use of Genetically Encoded Fluorescent Indicator (GEFI) lines has revolutionized real-time in vivo studies of second messenger dynamics in plants. This approach already revealed crucial …
