A stationary digital tomosynthesis system using 43 carbon nanotube (CNT) field emission X-ray sources has been developed to overcome some issues in traditional chest tomography synthesis systems using a single X-ray source. This new system utilizes CNTs to digitize X-ray source, allowing for the acquisition of high-resolution 3D X-ray images without motion blur. The system has been compared to a traditional tomosynthesis system using a thermionic source based on filament. This study reports a multi-array X-ray device, in which a body part made of an insulating material, which is a non-metallic material, provides a natural insulating environment to generate high-performance X-ray devices.

A multi-beam compact tomosynthesis system has been developed to acquire chest X-ray images and provide reconstructed 3D X-ray images. The system uses 43 field emission X-ray sources based on carbon nanotubes (CNTs). The CNT-based X-ray source consists of an anode array, gate array, and electron gun (e-gun) array and is stationary while the digital X-ray detector moves. To analyze 3D data of the electron emission trajectory in the multi-beam X-ray source, simulation software which is CST Particle Tracking Studio was used. In this developed system, we applied a vacuum external projection type X-ray source device. Specifically, it relates to a vacuum externally protruding type X-ray source device that can be easily replaced by protruding the lower part of the unit X-ray source to the outside of the vacuum.
