Example ⁸²Rb generator activity output profiles from a RUBY-FILL^® test elution performed at 20 mL·min⁻¹. ⁸²Rb eluate activity (MBq/s, blue) as measured at the output of the patient infusion line over time. Total activity delivered to the patient or calibration vial (MBq, solid orange line) increases over-time according to the integrated area under the ⁸²Rb eluate time–activity curve. Activity measured in a dose-calibrator vial (CardioGen-82^®) increases initially over time, but then reaches a steady-state maximum value (MBq, dashed orange line) which is lower than the integrated total activity
