US Patent 7771117 - Nanostructured emitter for dental x-ray
http://ip.com/patent/US7771117
Size and power requirements create difficulties for medical x-rays and the situation is exacerbated when dealing with oral x-rays. This patent from Korea Electrotechnology Research Institute teaches a system using nanotube or nanowire electron emitters in forming a miniature low power X-ray source for dental examinations. Claim 1 reads:
1. An oral X-ray tube system comprising:
a hand-held body having a pen-shape;
an X-ray emission module emitting X-rays using a cathode comprising a chipped nano-structured material,
wherein the X-ray emission module is separable from the body.
