Double scattering versus Scanning

Double Scattering

• Distal conformality

• Easier to QA

• No intensity modulation

• Difficult for dose painting

• Time consuming

Scanning

• Distal + proximal conformality

• More difficult QA

• Intensity Modulation

• Dose painting

• Faster to deliver \ higher

doserate

• Easier to adapt
