Flood histogram obtained at an event rate of (a) 7.8 kcps, (b) 49.7 kcps, (c) 101 kcps and (d) 132 kcps. The estimated corresponding 18F activities were 11.2, 109, 230 and 305 uCi. The bias voltage was 35.0 and temperature was −10 °C. A 250–650 keV energy window was applied to each crystal to select events.
