Design Of X-Ray Source For Real-Time Computed Tomography, Wesley William Tucker
Design Of X-Ray Source For Real-Time Computed Tomography, Wesley William Tucker
Doctoral Dissertations
"The reduction of motion blur in computed tomography (CT) drives the current research for multisource CT. Due to their compact nature, the current multisource systems utilize stationary angled anodes. Unfortunately, these configurations neither simplify the imaging geometry, nor satisfy the need for managing the high thermal loads demanded by real-time CT (30 acquisition frames per second). To add to the current field of knowledge, two x-ray tube concepts are presented in this dissertation. First, a simulation of transient thermal analysis was performed on a compact transmission-type x-ray tube anode operating in pulse-mode. A correlation was found between deposited beam power …
Design, Product Development And Risk Assessment Of Tin (Sn) Ring Electrodes As A Substitute To Silver-Silver Chloride (Ag Agci) Ring Electrodes For High Definition Transcranial Direct Current Stimulation (Hd-Tdcs), Linford Leitch
Dissertations and Theses
The objective of this research thesis is to test the viability of Tin (Sn) ring electrodes as an inexpensive alternative to sintered Silver-Silver Chloride (Ag|AgCl) ring electrodes for High Definition – transcranial Direct Current Stimulation (HD-tDCS). Throughout our initial bench top testing of tin electrodes in combination with a ‘conductive electrode gel’, the passing of a 2mA direct current on agar block showed the formation of white cloud around the anode electrode and a cluster of air bubbles on the cathode. The analysis of pertinent literature indicates that the white milky substance produced during the stimulation at the anode is …
