  • Radiation detection module, radiation detector and radiological imaging apparatus
    Patent number: 7247860
    Abstract: A radiation detection module and radiological imaging apparatus capable of improving spatial resolution. A semiconductor radiation detector includes a plurality of semiconductor radiation detector elements and conductive members which are copper plates. A detector element provides an anode electrode on one of facing sides of a semiconductor region and a cathode electrode on the other side. The respective detector elements are arranged in parallel in such a way that the cathode electrodes and anode electrodes face each other respectively, and the anode electrodes are electrically connected together and the cathode electrodes are electrically connected together via the conductive members respectively.
