Multi-layered bolus
A range-compensation filter constructed from plastic for each proton beam plays a crucial role in forming the treatment volume corresponding to the targeted tumor profile.
Based on the bolus shape defined during therapy planning, 3 mm thick plates of bolus material are punch-pressed at high speed. After inspection of the shape, these plates are placed in a dedicated case and formed into a bolus block.
Product Features
High-precision processing and inspection
The bolus is divided into 3 mm thick plates and processed by a high-precision turret punch press machine. The bolus is then optically inspected to achieve an overall processing accuracy of < 1 mm.
High-speed processing and inspection
Processing the maximum target volume bolus (200 · 150 · 195 mm) takes no longer than 1 hour and less than 30 minutes for a standard size bolus.
No need to deburr
The punching process suppresses burr formation and requires no deburring after processing. The block manufacturing method also automates the flow of processing and inspection and simplifies the entire manufacturing process.
Turret punch press
The bolus material plate is punch pressed with a regular die. The punch-pressed plates are multi-layered and placed onto the bolus case.
