A Novel Static CT System: The Design of Triple Planes CT and Its Multi-Energy Simulation Results

In this paper, we propose a novel static CT system: triple planes CT (TPCT) system. Three source-detector planes in different horizontal directions are placed in the system. Line-array carbon nanotube sources with different voltages and sandwich detectors are used. Compared to conventional cone-beam...
