Fabrication of ZnO nanowire cold cathode flat panel X-ray source module for adaptive X-ray imaging

Flat panel X-ray source enables the possibility of adaptive X-ray imaging which could achieve close range imaging. In this study, a flat panel X-ray source module based on ZnO nanowire field emitter arrays was fabricated. High resolution projection imaging using the module was achieved, which demonstrated the feasibility of adaptive X-ray imaging using nanowire FEA flat panel X-ray source.
