Summary
Additively manufactured implants in head and neck cancer radiotherapy can cause dose errors. Accurate density assignment is crucial for safe and effective radiation treatment planning.
Area of Science:
- Medical Physics
- Radiotherapy
- Oncology
Background:
- Additively manufactured (3D-printed) implants are common in head and neck reconstruction.
- These implants present challenges in assigning accurate radiologic density for radiotherapy planning.
