    A new computer program, brachy-spread, simplifies brachytherapy treatment planning by allowing interactive adjustments to source activity and duration. This tool significantly reduces the time needed for optimizing radiation doses in gynecological and complex brachytherapy applications.

    Area of Science:

    • Medical Physics
    • Radiation Oncology
    • Computational Biology

    Background:

    • Brachytherapy requires precise loading of radioactive sources for effective dose delivery.
    • Manual calculation and adjustment of brachytherapy parameters are time-consuming and complex.

    Purpose of the Study:

    • To develop and implement an interactive computer program for optimizing brachytherapy loading.
    • To reduce the time and complexity associated with treatment planning in brachytherapy.

    Main Methods:

    • Implementation of a spreadsheet-like interface for interactive adjustment of source activity and implant duration.
    • Real-time recalculation of dose rates, total doses, and source contributions at defined calculation points.
    • Rapid display of isodose curves using precalculated fractional dose tables.
