We propose to develop a novel x-ray pixel beam array micro-RT system using carbon nanotube field emission. The radiation field shape, intensity modulation, and their variation with time are defined electronically by activating a selected set of CNT field emission x-ray pixel beams. Once developed the micro-RT will be integrated with the CNT micro-CT already developed by our collaborator Dr. Zhou’s group to form an integrated micro-CT-RT system. The micro-CT-RT system is expected to deliver image-guided (IGRT) and intensity-modulated (IMRT) irradiation analogous to the state of the art radiotherapy many of our patients receive today but at the scale of a mouse.
