Carbon nanotube field emission based x-ray pixel array micro-RT

DESCRIPTION (provided by applicant): Carbon nanotube field emission based x-ray pixel beam array micro-RT system Carbon nanotube (CNT) field emission (FE) technology has been successfully used to develop novel radiographic imaging systems to meet the current and anticipated needs in both cancer biology research and medical application. To date, few works exist that explore the feasibility of this unique nanotechnology for radiation delivery devices. There is a growing need for ultra-high spatial and temporal resolution image-guided small animal irradiation and researchers today are struggling to meet the challenge using conventional technologies. The need for high-resolution small animal research tools is expected to grow drastically in the near future as new biomarker and biosensor agents, many are nanotechnology-based, coming out of the research and development pipeline for preclinical study for both intended and unintended effects including radiation- drug interaction. Our ultimate goal is to develop a nanotechnology based micro-CT-RT system that is capable of unprecedented temporal (
