Physics Bucharest 2017

CONCLUSION

• Broadbeam methods • Accurate ONLY for simple fields, homogeneous volumes. • Pencil beam algorithm • Used to overcome limitations with irregular fields, only AAA takes lateral scatter into account • Convolution algorithms • Provide high accuracy with inhomogeneities • Monte Carlo • Solution of the Boltzman transport equation • Please get to know your planning system’s dose algorithm and it’s limitations
