摘要
An energy-spectrum CT imaging system (100), data acquisition method and energy-spectrum CT image reconstructing method thereof. The energy-spectrum CT imaging system (100) comprises: a photon detector (120) having a plurality of pixels (1202). The data acquisition method for the energy-spectrum CT imaging system (100) can comprise: performing, at a plurality of projection angles and from the photon detector (120), data acquisition on photons passing through an imaged object (115). For each of the projection angles, the data acquisition method comprises: acquiring data from the photon detector (120) according to a plurality of randomly distributed pixel address codes.
