Thermoplastic Sheet Bolus

Designed for challenging, hard-to-form anatomical regions—including the chest wall, nose, parotid, groin, and ears—IOS thermoplastic bolus easily conforms to irregular surfaces to achieve optimal fit. Its attenuation properties are comparable to other polymer-based bolus materials, ensuring reliable dose delivery.

The material softens quickly in hot water or an oven, enabling efficient molding that reduces setup time while minimizing air gaps and day-to-day variability.
