1. A hybrid scintillation/direct conversion computed tomography (CT) imaging system comprising:

  • a gantry, wherein said gantry defines a patient cavity and includes an x-ray source and a radiation detection apparatus, wherein said radiation detection apparatus includes a first radiation detector and a second radiation detector and wherein said x-ray source and said radiation detection apparatus are rotatingly associated with said gantry in an X-Y plane so as to be separated by said patient cavity, wherein said first radiation detector is a different type of detector than said second radiation detector, said second radiation detector configured to count attenuated x-rays and measure the energy of said attenuated x-rays;

    a patient support structure movingly associated with said gantry in a Z axis substantially transverse to said X-Y plane so as to allow communication with said patient cavity; and

    a processing device, wherein said processing device is communicated with said radiation detection apparatus.
