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;
• a source support having a rectangular plate extending in a vertical direction to support the plurality of sources;
• a plurality of anodes for emitting X-rays and disposed to face the plurality of sources;
• and
• an anode support having a rectangular plate extending in the vertical direction to support the plurality of anodes,
• wherein the plurality of anodes have a plurality of protrusions each of which extends in a horizontal direction,
• wherein the rectangular plate of the anode support incudes a plurality of holes through which the plurality of protrusions pass,
• wherein each of the plurality of anodes has a reflective surface where the electrons collide, X-rays are emitted from reflective surfaces of the plurality of anodes as a result of collision of the electrons, and each of the plurality of anodes faces a corresponding source among the plurality of sources, and
• wherein each anode of the plurality of anodes is rotatable around a protrusion formed in the each anode of the plurality of anodes and passing through the rectangular plate of the anode support to adjust each angle of the reflective surfaces is independently so that the X-rays emitted from each of the plurality of 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.
