Area of Science:

  • Medical Physics
  • Radiotherapy
  • Computational Biology

Background:

  • Three-dimensional radiotherapy treatment planning requires optimization of beam weights.
  • Clinical considerations necessitate incorporating relative structure importances into planning algorithms.
  • Existing methods may not always yield feasible solutions within dose constraints.

Purpose of the Study:

  • To develop a computer software tool to aid treatment planners in selecting beam weights for 3D radiotherapy.
  • To implement an interactive program that incorporates a feasibility search algorithm.
  • To allow for clinical judgment in plan acceptability when dose constraints are challenging.

Main Methods:

  • Development of a user-friendly software tool with an embedded feasibility search algorithm.
