1. A Positron Emission Tomography (PET)-Magnetic Resonance Imaging (MRI) combination apparatus, comprising:

  • an MRI bore configured to capture an MR image of an object placed in an imaging space;

    a PET detector installed inside the imaging space of the MRI bore, and comprising a plurality of scintillation crystal arrays, each having a plurality of scintillation crystals arranged in a ring shape, wherein the plurality of scintillation crystal arrays is arranged in a longitudinal direction so as to extend a axial field of view (FOV);

    a PET circuit configured to amplify and process PET signals, wherein the PET circuit is installed outside the MRI bore to avoid or minimize influence of a magnetic field produced in the MRI bore; and

    a cable connecting the PET detector to the PET circuit.
