Abstract
A radiation sensing device including a collimator, a disc-shaped scintillation crystal in close proximity thereto; at least three substantially parallel photomultiplier tubes adjacent to one side of the scintillator and circuitry for locating a scintillation in the crystal. In particular, the circuitry includes a diode bias to correct for distortion and non-uniformity which results from placing the photomultiplier tubes adjacent to the scintillator.
