Episode notes
GPU-Powered Faster Planning
- RapidArcDynamic uses GPUs to compute highly complex radiotherapy plans much faster than previous systems.
- This enables more optimal, time-efficient treatment planning without sacrificing precision.
Always Use Preplanning And Onboard Imaging
- Schedule a CT design scan before treatment to map tumour location and movement accurately.
- Use onboard imaging on treatment days to confirm anatomy and adjust delivery as needed.
Dynamic Arc Delivery
- The machine delivers radiation while rotating around the patient, changing beam shape and intensity dynamically.
- This allows targeted dosing from multiple angles to concentrate dose on tumours and spare healthy tissue.
