Abstract
Disclosed is a field emission-type tomosynthesis system including a vacuum body having a space therein; a plurality of sources provided inside the body, wherein each of the sources emits a plurality of electrons; and a plurality of anodes disposed inside the body to face the sources and responsible for emitting a plurality of X-rays, wherein each of the anodes faces a corresponding source among the sources, and the electrons collide with each of the anodes to generate X-rays, wherein the X-ray emission angle of each of the anodes is capable of being independently adjusted so as to focus the X-rays emitted toward an object located outside the body. With this configuration, a plurality of X-rays is focused on an object and is emitted to the object to obtain information, and the information is synthesized, thereby improving the reliability of information about the object.
