A new silicone nasal radiation carrier was fabricated using a rubber base impression. This flexible, shielded device accurately positions radioactive sources, reducing radiation exposure during nasal treatment.

Area of Science:

  • Medical Devices
  • Radiation Oncology
  • Materials Science

Background:

  • Nasal cavity radiation therapy requires precise source placement.
  • Existing methods may have limitations in accuracy and radiation shielding.
  • Flexible carriers can improve patient comfort and treatment delivery.

Purpose of the Study:

  • To describe the fabrication of a novel flexible shielded afterloaded silicone nasal radiation carrier.
  • To evaluate the carrier's ability to accurately position radioactive sources.
  • To assess the reduction in radiation exposure achieved by the carrier.

Main Methods:

  • A rubber base impression of the nasal cavity was utilized.
  • A silicone radiation carrier was fabricated incorporating plastic tubes for afterloading.
