Flat-panel Addressable Cold-cathode X-ray Source based Stationary CT Architecture

Stationary CT system can not only improve image quality with motion artifacts reduction, but also can help to visualize dynamic process. How to develop a reliable stationary CT is a very challenging task. To address with this challenge, we proposed a totally new addressable cold cathode flat-panel X-ray source based stationary CT architecture, entitled as Flat-panel Addressable Nanowire-cold-cathode Stationary (FANS) CT scanner. The FANS scanner is a small and cheap system since the low-cost compact flat-panel X-ray source is used. Additionally, it is also a stationary CT system since the flat-panel X-ray source has the ability of fast switching. Finally, our FANS system provides extinguished image quality with incorporating superior regularization priors. The experiments on numerical and clinical datasets further demonstrate the feasibility of our proposed FANS CT imaging system.
