Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Radiotherapy Planning

Background:

  • Treating inclined lesions with non-vertical or non-horizontal radiation beams presents significant planning challenges.
  • Patient support assembly and collimator rotations add complexity to radiotherapy planning, potentially impacting treatment accuracy.

Purpose of the Study:

  • To describe a simplified empirical approach for planning radiation therapy treatments involving inclined lesions.
  • To address the complexities arising from non-standard beam angles and equipment orientations in radiotherapy.

Main Methods:

  • An empirical method utilizing a protractor and calculator for treatment planning is detailed.
  • The approach facilitates plan generation in planes other than the central axis, accommodating complex lesion geometries.

Main Results:

  • The proposed empirical method offers a practical solution for planning treatments with inclined lesions.
  • Discussion includes a caution regarding the accurate location of the Source-Axis Distance (SAD) point in non-standard setups.

Conclusions:

  • This empirical approach simplifies the planning of radiation therapy for inclined lesions, even with complex beam configurations.
  • Accurate determination of key reference points, like the SAD point, is crucial for successful treatment outcomes in these scenarios.
