ClearSight Bolus

See the setup.
Clearly.

Keep tattoos, positioning lasers, and air gaps in view. Crystal-clear material brings visibility to the details of your patient’s setup.

100%Transparent material

A clear view.
A practical difference.

ClearSight allows you to see through the bolus, even in a dim treatment room. Its transparent material does not yellow under radiation exposure.

01 / CONFORM

Made to stay close.

An inherently adherent surface helps the bolus conform to the patient, with air gaps visible through the material.

02 / CUSTOMIZE

Cut. Layer. Adapt.

Cut with scissors to suit the treatment area. Sheets adhere to one another without bonding permanently, allowing layering for custom thickness.

03 / REUSE

Washable by design.

The semi-sticky surface retains its inherent adherence after washing and drying. No gooey center to work around when cutting.
