Abstract

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. In this study, we have developed the digital tomosynthesis system which is an improvement over conventional tomosynthesis systems as it is lighter, is easier to load the CNT e-gun, eliminates motion blur since the gantry is fixed, and provides fast and high-resolution images because of the reduction of the focal spot size with the use of multiple CNT-based X-ray sources.
