A novel, cost-effective method for adjustable field shaping in external-beam radiation therapy is presented. This system enables rapid setup and daily adjustments for high-quality, reproducible treatment fields.

Area of Science:

  • Medical Physics
  • Radiation Oncology

Background:

  • External-beam radiation therapy requires precise shaping of radiation fields.
  • Current methods for field shaping can be complex or costly.

Purpose of the Study:

  • To introduce a simple, adjustable field shaping system for radiation therapy.
  • To provide a cost-effective solution for treatment field setup.

Main Methods:

  • Utilized shielding blocks attached to specially designed flanges and a blocking tray.
  • Allowed for a wide latitude of block placement on the tray.

Main Results:

  • The system demonstrated cost-effectiveness and rapid setup capabilities.
  • Enabled daily blocking adjustments when necessary.
