Area of Science:

  • Radiotherapy Physics
  • Medical Physics
  • Radiation Oncology

Context:

  • Shielding blocks are crucial in radiotherapy for precise radiation delivery.
  • Standard accessory mounting devices are used to fix blocks on linear accelerator (linac) heads.
  • Existing mounting devices present significant disadvantages and potential for errors.

Purpose:

  • To discuss the drawbacks of current block mounting devices for linacs.
  • To present two novel modifications to improve shielding block mounting.
  • To introduce a secure locking mechanism to prevent mounting errors.

Summary:

  • The study identifies limitations in standard linac accessory mounting devices for radiotherapy shielding blocks.
  • Two improved designs are proposed: one with adjustable focus-support distance for standard lead blocks, and another featuring gliding planes for easier insertion of heavy, custom blocks.
