A new, rugged neck-thyroid phantom was developed for in vivo monitoring calibration. This anthropomorphic phantom simulates radioactive iodine isotopes and varying adipose tissue, ensuring accurate thyroid measurements.

Area of Science:

  • Medical Physics
  • Nuclear Medicine
  • Biophysics

Background:

  • The Canadian National Calibration Reference Center for In Vivo monitoring requires reliable calibration tools.
  • Accurate in vivo thyroid monitoring is crucial for assessing radioactive iodine exposure.
  • Existing phantoms may lack robustness or specific simulation capabilities.

Purpose of the Study:

  • To design and construct a robust, anthropomorphic neck-thyroid phantom for the Canadian Thyroid Intercomparison Program.
  • To create a cost-effective phantom capable of simulating 125I and 131I isotopes.
  • To develop a phantom that can mimic variable adipose tissue layers for realistic monitoring scenarios.

Main Methods:

  • The Human Monitoring Laboratory designed and manufactured a novel neck-thyroid phantom.

  • The phantom incorporates anthropomorphic features and specific thyroid inserts.
  • Design focused on ruggedness for mail distribution and cost-effectiveness.

    • Main Results:

    • The developed phantom is rugged, preventing leaks during mail distribution.
    • It accurately simulates both 125I and 131I thyroid inserts.
    • The phantom allows for the simulation of different adipose tissue thicknesses.

    Conclusions:

    • The new neck-thyroid phantom meets the requirements for the Canadian Thyroid Intercomparison Program.
    • Its robust design and simulation capabilities enhance the accuracy of in vivo thyroid monitoring.
    • This phantom represents a cost-effective advancement in calibration standards for radioactive iodine monitoring.
