The high count rates in Dual Head Coincidence Imaging (DHCI) produce significant randoms fractions in the acquired data. The authors simulated random coincidence data from uniform cylinders in a DHCI system with 51 cm/spl times/37 cm detectors spaced 63 cm apart. The randoms were normalized as if th...
