Field emission-type tomosynthesis system, emitter for field emission-type tomosynthesis system, and method of manufacturing emitter

A field emission-type tomosynthesis system, comprising:

• a plurality of sources for generating electrons;
• and
• a plurality of anodes responsible for emitting X-rays and disposed to face the sources, wherein each of the anodes has a reflective surface where the electrons collide, X-rays are emitted from the reflective surfaces as a result of collision of the electrons, and each of the anodes faces a corresponding source among the sources,
• wherein each angle of the reflective surfaces is independently adjustable so that the X-rays emitted from each of the anodes are directed at one point.

A method of manufacturing an emitter for a field emission-type tomosynthesis system, wherein the field emission-type tomosynthesis system comprises a plurality of sources provided inside a vacuum body having a space therein and responsible for emitting electrons, and the method comprises a step of preparing a substrate;

• a step of forming a pattern by forming a plurality of holes through perforation in the substrate;
• a step of growing carbon nanotubes (CNTs) on the substrate on which the pattern has been formed by the holes;
• and
• a step of heat-treating the CNTs grown on the substrate at high temperature.
