Abstract

The carbon nanotubes (CNTs) were used as an X-ray source in a micro computed tomography (CT) system. Several types of substrates have been employed to enhance the resolution, with a single-pillar substrate demonstrating the potential to produce high flux, high-resolution images. The current density of 4 A/cm2 was achieved and the focal spot size of 863 μm was calculated through X-ray image. This approach was applied to reconstruct CT images of dental phantoms, and it was successful.
