What term refers to the measure of consistency in dose calibrator output?

The term that refers to the measure of consistency in dose calibrator output is constancy. In the context of medical imaging and radiopharmacy, constancy specifically relates to how consistently a dose calibrator provides the same readings for a radionuclide over time, assuming the same radioactive source is used under the same conditions. This measure is crucial to ensure accurate dosing for patient safety and effective treatment.

Regular quality control procedures employ constancy tests to verify that the dose calibrator is functioning correctly over time. This means that any significant deviation in readings can indicate the need for recalibration or maintenance, ensuring that the equipment remains reliable for clinical use.
