Development and Trend of Radiation Imaging Technology for Large Object

A comprehensive review on various large object radiation imaging technologies and their applications was introduced in this paper. The imaging principle, technical characteristics, development status and trend of those techniques were investigated, such as X/γ-ray transmission imaging, backscatter imaging, CT reconstruction and fast neutron imaging, to be helpful for the development of radiation imaging technology for large object in the more safe, efficient, precise and smart way.
