Dual energy CT reconstruction method for incomplete high energy data

Dual energy computed tomography (DECT) has played an important role in homeland security because of its capability in material discrimination, which makes it more competitive in explosives detection than normal single energy CT. However, the system cost from the high energy detector crystal is one of the primary obstacles to the widespread deployment of DECT. In this paper, we proposed a novel DECT system scheme reconstruction method dealing with the incomplete high energy data problems. Experimental results demonstrate the high energy detector can be reduced significantly with little image degradation.
