Spectral CT imaging has gained a lot of attention because of its potential in improving imaging quality or lower radiation dose.Photon counting detector is the primary choice for spectral CT imaging.However,stable and large area PCD have not been commercially available yet in these days.We proposed a multi-energy scanning strategy with conventional CT which is easy to implement and introduce almost no extra dose and add no extra time of scan compared to traditional CT.A structural prior is formed from multi-energy data to represent the common structural information among multi-energy images.This could be an intermediate solution for spectral CT imaging.It is also very useful to high energy imaging at the energy level where PCD is difficult to cover.
