The Geometry Test

January 19, 2015
Ann Marie Alessi, BS, CNMT, NCT, RT(N), Product Sales Manager, Nuclear Medicine, Biodex Medical Systems, Inc.

The geometry of the container (syringe or vial) that is used to measure a radioactive source can be a cause of assay errors in dose calibrators. Specifically, if there is a difference in the container used to obtain initial calibration settings and the container used to assay dosages in clinical practice. Ideally, the geometry of the standard source should be identical to the geometry of the source being measured. If the source geometry is not identical, the error in the measurement should be quantified and, if significant, either a new calibration setting determined or a correction factor applied. >>
