Automated Syringe Dose Assay System

Radiation Shielding, Inc. and Pinestar Technology, Inc. have introduced a new automated radiopharmaceutical syringe dose assay system (ARSDAS) that will significantly reduce the radiation exposure that technicians receive as they assay syringes prior to patient administration.

The system features a lead-shielded cabinet with a lead-glass window that is mounted on top of the system control cabinet. The shielded cabinet contains a robotic arm, an opening to a shielded dose calibrator (2 inches lead shielding), an opening to a shielded sharps container (2 inches lead shielding), a docking station for a syringe shield, a docking station for a syringe pig, and two hinged, shielded front doors.

System Benefits

Traditionally, the technician manually performs the assay of the syringe behind an L-block shield. This process results in the technician receiving a significant dose of radiation to their hands. The new automated radiopharmaceutical syringe dose assay system eliminates the radiation dose to the technician in compliance with the ALARA philosophy.

System Operation

A. Syringe shield utilized

  1. The technician opens the right shielded door and places the pig with the syringe dose into the pig docking station and removes the pig cap. The technician places the syringe shield into the syringe shield docking station and closes the door.
  2. The technician presses the “Start” button.
  3. The robotic arm removes the syringe from the pig and places the syringe into the shielded dose calibrator where it is assayed. After the assay is completed, the robotic arm places the syringe into the syringe shield.
  4. The technician opens the right shielded door, places the top back on the empty pig and removes the pig. The technician removes the syringe in the syringe shield and closes the door.

B. Syringe shield not utilized

  1. The technician opens the right shielded door and places the pig with the syringe dose 1. into the pig docking station, removes the pig cap and closes the door.
  2. The technician presses the “Start” button.2.
  3. The robotic arm removes the syringe from the pig and places the syringe into the 3. shielded dose calibrator where it is assayed. After the assay is completed, the robotic arm places the syringe back into the pig.
  4. The technician opens the right shielded door, places the top back on the pig, removes 4. the pig and closes the door.

Power Outage

In the event of a power outage, the technician can open the two shielded cabinet doors and use the lead-glass window and lead shielding as he would an L-block shield and perform the assay manually.
