    Area of Science:

    • Medical Physics
    • Radiation Oncology
    • Radiotherapy Technology

    Background:

    • Traditional radiotherapy planning uses Paterson-Parker rules for source distribution.
    • Existing methods often involve repositioning the same source pencil multiple times, increasing treatment duration.
    • Optimizing source arrangement is crucial for efficient and effective radiation delivery.

    Purpose of the Study:

    • To investigate an alternative arrangement of Cathetron source pencils for radiotherapy moulds.
    • To minimize irradiation time by employing multiple types of source pencils.
    • To analyze dose distributions for various mould configurations and treatment distances.

    Main Methods:

    • Developed and evaluated a novel arrangement for Cathetron source pencils.

  • Calculated dose distributions for planar, linear, and cylindrical moulds.
  • Assessed the impact of different treating distances on dose patterns.

    • Main Results:

    • The proposed alternate arrangement effectively utilizes multiple pencil types, reducing overall irradiation time.
    • Dose distributions were successfully obtained for diverse mould sizes (three planar, two linear, two cylindrical).
    • The study provides data on dose patterns relevant to clinical application.

    Conclusions:

    • The new Cathetron source pencil arrangement offers a more efficient approach to radiotherapy planning.
    • This method has the potential to significantly decrease patient treatment times.
    • The findings support the implementation of optimized source configurations in clinical practice.
