    Area of Science:

    • Medical Physics
    • Radiation Oncology
    • Radiotherapy

    Background:

    • Estimating dose for brachytherapy treatments presents challenges in treatment scheduling.
    • Existing ret dose estimation methods lack consistency, leading to disparities in scheduling.

    Purpose of the Study:

    • To review existing ret dose estimation schemes for brachytherapy.
    • To identify the cause of disparity in current methods.
    • To propose a consistent system for brachytherapy treatment scheduling.

    Main Methods:

    • Literature review of various ret dose estimation schemes.
    • Analysis of scheme variability with changes in the exponent of time.
    • Evaluation of the CRE (nominally Constant Rate Effect) system for consistency.

  • Development of a nomogram for CRE estimation.
  • Main Results:

    • The CRE system demonstrates minimum variability, making it suitable for treatment scheduling.
    • Average exponent of time and normalizing constant are used to evaluate CRE for brachytherapy.
    • Ready-made CRE estimations for various dose rates and treatment times are provided.

    Conclusions:

    • The CRE system is the most consistent method for solving brachytherapy treatment scheduling problems.
    • The developed nomogram simplifies CRE value determination for different treatment parameters.
