Figure 2 A comparison of 4D dose and RT dose.

Conclusion:

The workflow of pre-review free breathing by 4D proton dose calculation was built successfully. It can help clinics find the dose uncertainty before treatment towards a safe and robust proton therapy involving breathing.

Keywords: proton therapy, monte carlo, free breathing
