Giraffe is a high resolution multi-layer ionization chamber, which consists of 180 large 12 cm diameter electrodes.
Compatible with: Synchro-Cyclotron, Cyclotrons, Proton Therapy, TG224
Used for: Annual QA PT, Monthly QA PT
Rapid Particle Therapy Commissioning
- 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 PBS verification within one second
- Check your complete Bragg peak depth dose curve for single spot beam delivery
Minimize loss of data collection
- Save time with reduced effort to correct data at TPS level. Verify the TPS library periodically without needing to set up the water tank.
