A customized head and neck support system

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.
