Abstract
Computed Tomography (CT) using Carbon Nanotube (CNT) x-ray source is a technique of generating reconstruction images of the structure of teeth sample. A proto type CNT x-ray CT was designed for medical imaging to examine whether it could be used to analysis the equipment of medical and industrial application. The CNT field emitter array was grown on silicon substrate through a resist-assisted patterning (RAP) process. The field emission properties showed a gate turn-on field of 3.8 V/μm at an anode emission current of 0.5 mA. The author demonstrated the x-ray source with four electrode structures utilizing the CNT emitter. The acquisitioned images were reconstructed by filtered back projection (FBP) method.
