Radioisotope delivery system with multiple detectors to detect gamma and beta emissions

An infusion system comprising:

• a frame that carries a beta detector, a gamma detector, a strontium-rubidium radioisotope generator that generates a radioactive eluate via elution, and a controller communicatively coupled to the beta detector and the gamma detector,
• the beta detector is positioned to measure beta emissions emitted from the radioactive eluate,
• the gamma detector is positioned to measure gamma emissions emitted from the radioactive eluate,
• the controller is configured to determine an activity of rubidium in the radioactive eluate based on the beta emissions measured by the beta detector and determine an activity of strontium in the radioactive eluate based on the gamma emissions measured by the gamma detector,
• the controller is configured to determine a cumulative volume of the radioactive eluate generated by the radioisotope generator and to prevent a patient infusion procedure if the cumulative volume of the radioactive eluate exceeds an allowable limit, and
• the controller is configured to determine a cumulative activity of rubidium during a patient dosing procedure, compare the cumulative activity of rubidium to a threshold stored in memory, and cease delivering eluate to a patient if the cumulative activity of rubidium exceeds the threshold.
