Summary
This study determined optimal electron energies for Intraoperative Irradiation Therapy (IORT) to ensure uniform radiation dose delivery. Accurate target thickness calculation is crucial for effective IORT and patient safety.
Area of Science:
- Medical Physics
- Radiation Oncology
Background:
- Intraoperative Irradiation Therapy (IORT) requires precise target thickness computation for effective radiation delivery.
- Accurate dosimetry is critical during surgical radiation procedures.
Purpose of the Study:
- To compute target thickness for Intraoperative Irradiation Therapy (IORT).
- To design a radiation pattern for uniform irradiation distribution within the target.
- To establish optimal parameters for IORT delivery.
Main Methods:
- Utilized Monte Carlo simulations to model the experimental setup.
- Investigated electron flux variations across different target tissue thicknesses.
- Validated simulation data with experimental results from an electronic board.
Main Results:
- Identified 6 MeV electrons as suitable for determining target thickness using Poly Methyl Methacrylate (PMMA) phantoms.
- Higher electron energies (e.g., 6 MeV) are effective for uniform radiation distribution and treatment.
- Increased phantom thickness correlates with longer radiation times, necessitating scanning-based management.
Conclusions:
- Precise calculation of remaining tissue thickness and irradiation time is essential post-tumor removal in IORT.
- Patient safety requires protection against overexposure, with radiation doses prescribed and monitored by oncologists.
