Giraffe PT

Overview

Check your complete Bragg Peak depth dose curve distribution for single beam spot delivery

The Giraffe PT is a high-resolution multi-layer ionisation chamber, which is consisting of 180 large 12 cm diameter electrodes

• Instant absolute range verification for weekly & monthly QA
• 3x faster commissioning of your particle therapy rooms
• Reconstruct the Bragg-peak for a single spot within seconds
• Verify the clinical range of up to 230 MeV

Instant daily PBS verification within one second

• Check your complete Bragg Peak depth dose curve distribution for single beam spot delivery

Minimise loss of data collection

• Safe time with reduced effort to correct data at TPS level. Verify the TPS library periodically without needing to set up the water tank.
