A Current Mode Energy-Resolved CT Using Several Kinds of Scintillators

For computed tomography (CT) with the energy information of X-rays (energy-resolved CT), the authors have been developed a new detector system, "transXend" detector. The transXend detector measures X-rays as electric current and gives energy distribution after analysis. To apply the principle of the transXend detector for the use of fan or cone beam X-rays, the authors have reported two-dimensional transXend detector using stripe metal absorbers and a flat panel detector (FPD). In this paper, the energy-resolved CT is demonstrated using a FPD with different kinds of scintillator plates. Next, the possibility of using a scintillator plate which consists of various stripe scintillators instead of stripe metal absorbers for a two-dimensional transXend detector is shown.
