Classification: CPC A  G | IPC A  G

Claim 15:
16. The infusion system of claim 10, wherein the controller is communicatively coupled to the multi-way divergence valve and configured to control flow from the eluate line to a select one of the infusion tubing line and the waste line via the multi-way divergence valve; and
the controller is further configured to:
control the pump to pump the eluant through the strontium-rubidium radioisotope generator and generate the radioactive eluate flowing through the eluate line to the waste line and the waste container,

control the beta detector to measure the beta emissions from the radioactive eluate flowing through the eluate line to the waste line and determine therefrom the activity of the radioactive eluate;
upon the activity of the radioactive eluate reaching a threshold level, control the multi-way divergence valve to place the infusion tubing line in fluid communication with the eluate line,
control the beta detector to measure the beta emissions from the radioactive eluate flowing through the eluate line to the eluate-receiving container via the infusion tubing line and determine therefrom an accumulated rubidium radioactive dose supplied to the eluate-receiving container,
upon determining that the accumulated rubidium radioactive dose has reached a Quality Control (QC) threshold level, control the pump to cease pumping the eluant through the strontium-rubidium radioisotope generator, thereby establishing a time from which an end of filling of the eluate-receiving container is measured,
control the gamma detector to measure the gamma emissions from the radioactive eluate in the eluate-receiving container within a constancy time window after the end of filling of the eluate-receiving container and determine therefrom an accumulated constancy gamma activity, and
calculate a constancy ratio based on the accumulated rubidium radioactive dose supplied to the eluate-receiving container and the accumulated constancy gamma activity.
