This study introduces a simple, non-graphical tool using trigonometric equations to check radiation therapy plan feasibility. It helps avoid beam obstructions and machine collisions, guiding patient repositioning for optimal treatment.

Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Treatment Planning

Background:

  • Treatment planning requires verifying beam paths and avoiding collisions with patient couches.
  • Current methods can be complex, hindering efficient plan assessment.

Purpose of the Study:

  • To develop a practical, non-graphical tool for assessing radiation therapy plan feasibility.
  • To provide guidance on patient repositioning to resolve detected beam obstructions.

Main Methods:

  • Examination of trigonometric relationships between treatment beams and patient couch.
  • Derivation of generalizable equations for feasibility checks.
  • Development of a simple, non-graphical planning tool.

Main Results:
