A rubidium-82 ( 82 Rb) elution system is described for use with clinical positron emission tomography. The system is self-calibrating with 1.4% repeatability, independent of generator activity and elution flow rate. Saline flow is switched between a 82 Sr/ 82 Rb generator and a bypass line to achieve a constant activity elution of 82 Rb. In the present study, pulse width modulation (PWM) of a solenoid valve is compared to simple threshold control as a means to simulate a proportional valve.
