Nova Scotia Health: A Comparison of Flexible Silicone Bolus Versus 3D Printed Rigid Bolus

This patient case demonstrates the clinical application of Adaptiiv’s technology used in radiation oncology through the fabrication of flexible silicone bolus that yields comparable plan metrics when compared to rigid 3D printed bolus for the treatment of an inner canthus tumor.

This is a great example of how Adaptiiv’s software can be effectively used to create patient-specific silicone bolus using 3D printed moulds which allow for a closer fit to the skin surface of complex patient anatomy, resulting in reduced air gaps and lower maximum dose to the PTV.

3D printed rigid bolus with a soft bolus plug has an air gap volume of 1.27cc.

Flexible silicone bolus created via 3D printed moulds has an air gap volume of 0.24cc.
