Summary
This study developed a method to measure radiation dose in breast tissue using 3D-printed phantoms. Findings show simulated doses were higher than measured, but reliable evaluation is possible.
Area of Science:
- Medical Physics
- Radiology
- Biomedical Engineering
Background:
- Accurate radiation dose assessment is crucial in mammography.
- Dose evaluation in breast tissue requires differentiating glandular and adipose components.
Purpose of the Study:
- To develop and validate a quantitative method for evaluating mean glandular dose (MGD).
- To compare simulated and measured radiation doses in breast phantoms.
Main Methods:
- Fabrication of breast phantoms with emulated glandular and adipose tissues using 3D printing.
- Quantitative glandular dose evaluation considering breast thickness, glandular ratio, and filters.
- Comparison of Monte Carlo simulations with glass dosimeter measurements.
Main Results:
- Increased glandular tissue ratio showed a non-significant dose decrease (~10%).
- Simulated doses were approximately 15% higher than measured doses.
- Silver and rhodium filters yielded mean simulated doses of 1.00 mGy and 0.72 mGy, versus measured 0.89 mGy and 0.62 mGy, respectively.
Conclusions:
- The developed quantitative method reliably evaluates mean glandular dose.
- Comparison of simulated and measured doses provides a robust approach for dose assessment in mammography.
