A new customized head and neck immobilization system for radiotherapy offers improved patient comfort and treatment setup reproducibility. This system better accommodates individual patient anatomy compared to standard headrests.

Area of Science:

  • Medical Physics
  • Radiotherapy Technology
  • Biomedical Engineering

Background:

  • Accurate patient immobilization is crucial for effective radiotherapy.
  • Standard immobilization devices may not adequately address individual patient anatomical variations.

Purpose of the Study:

  • To describe a novel customized head and neck immobilization system for radiotherapy.
  • To evaluate the conformity and effectiveness of this system.

Main Methods:

  • Development of a customized headrest conforming to the posterior head and neck.
  • Integration with a thermoplastic face mask molding to anterior head/face contours.
  • Comparison of customized supports with "standard" supports regarding shape and variability.

Main Results:

  • The customized system provides patient comfort.
  • The system demonstrates effectiveness in reproducing treatment setup.
  • Quantitative analysis indicates customized supports better address patient shape variabilities.

Conclusions:

  • Customized head and neck supports show greater variability in size and shape than standard headrests.
  • Clinical impression suggests improved reproducibility with customized supports.
  • The customized system is now a standard component of the immobilization protocol.
