Automatic radiopharmaceutical dose loader and calibrator for nuclear medicine injections
A simple and practical automatic device was designed and built to provide calibrated doses of radiopharmaceuticals into a syringe without the need for handling the radioactivity unnecessarily. Each radiopharmaceutical dose is loaded within the currently available calibration chamber and the amounts adjusted according to the accuracy of the commercial calibrators. This system consists of a small and compact unit which fits within the central cavity of the ionization chamber of the Capintec Radioisotope Calibrator CRC-4. At the base of the device is a lead shielded receptacle for a vial or a reservoir of radiopharmaceutical. The empty syringe is lowered into the central region of the ionization chamber where connection with the radiopharmaceutical supply reservoir is completed. A servo-motor adjusts the syringe plunger until the required quantity of radioactivity is loaded into the syringe. The amount of radioactivity in the loaded syringe is constantly displayed on the digital indicators of the calibrator. Once the proper quantity of radioactivity is loaded, the syringe is uncoupled and withdrawn between two halves of a lead shield. Radiopharmaceutical volume is indicated on the plunger rod. The use of translucent needle hubs permits the visualization of both blood and air when an intravenous injection is accomplished. This method reduced the radiation exposure and the need to handle the radioactive materials necessary for calibration of each dose. All operations occur within the ionization chamber of the dose calibrator minimizing radiation exposure to personnel.
