Disclosed are a radiation detector and a tomography imaging apparatus using the same. The radiation detector includes a plurality of image pixels that each include at least one counting pixel, and restore an image. The at least one counting pixel includes a radiation absorption layer, which converts incident photons into an electrical signal, and a photon processor that counts number of the photons, based on the electrical signal transferred from the radiation absorption layer. Number of the image pixels is smaller than number of the counting pixels. |
