Clearsight Bolus

A common challenge with other manufacturers’ bolus solutions is that their mustard-yellow colour can make it difficult to see tattoos, positioning lasers, and air gaps through the material - particularly in dark treatment rooms. Cortex’s new ClearSight Bolus is crystal clear enabling faster, easier setups than traditional bolus materials.

Transparent

• 100% transparent
• Does not yellow under prolonged radiation exposure
• Easy to visualize tattoos, lasers and air gaps
• Able to be layered for custom thickness while retaining transparency

Practical

•  No gooey centre like other bolus materials
• Able to be cut with scissors
• No need to wrap it in plastic
• Sticks to itself, but not permanently

Washable

• “Semi-sticky” surface inherent to material
• Retains stickiness after washing and drying

Technical Specifications

• Available in 30cm x 30cm and 40cm x 40cm sheets.
• The ratio of Zeff for ClearSight and water throughout the clinical range: 0.761 ± 0.02.
• Surface dose underneath ClearSight v. other popular Water Equivalent bolus products: -0.9% ± 2.3% for photons, 0.49 ± 1.8% for electrons.
• Change in photon and e- depth dose curves between ClearSight and water: negligible
