A new method uses POLYFORM thermoplastic to create custom radiation shielding molds for patients. This technique is faster and more comfortable than traditional methods, improving patient and dosimetrist experience.

Area of Science:

  • Medical Physics
  • Radiotherapy
  • Biomaterials

Background:

  • Radiation therapy requires precise patient surface contouring for accurate shielding.
  • Traditional methods for creating custom lead cut-outs involve plaster bandages or dental impression gels, which can be time-consuming and uncomfortable.

Purpose of the Study:

  • To introduce and evaluate a novel procedure for creating custom patient molds using POLYFORM thermoplastic for radiation shielding applications.

Main Methods:

  • POLYFORM thermoplastic was softened in warm water and molded to the patient's skin surface to create a negative mold.
  • Lead cut-outs were formed directly within the negative mold or by creating a positive mold from dental stone for thicker lead sheets.

Main Results:

  • The POLYFORM thermoplastic method provides a neat, fast, and comfortable alternative to traditional molding techniques.
  • The procedure allows for precise shaping of lead cut-outs to patient surface contours.

Conclusions:

  • The developed POLYFORM thermoplastic procedure offers an efficient and patient-friendly approach for fabricating custom radiation shielding for radiotherapy.
  • This method enhances comfort and reduces procedure time for both patients and dosimetrists.
