  • Radiography
    Patent number: 4153839
    Abstract: The specification discloses a scintillator crystal configuration which enables a group of crystals to be closely packed together, for example in a V-formation. Each crystal receives x-radiation through an input face, which is of small area, and emits light through an output face, to which a photodiode is preferably attached and which is therefore of larger area than the input face. Also disclosed is a medical radiographic apparatus incorporating an X-ray detector unit containing a number of such crystals.
