Since the publication of the AAPM TG105 report, an increasing number of clinics have acquired advanced dose calculation capabilities through fast Monte Carlo or linear Boltzmann equation solver-based algorithms provided by treatment planning system vendors.

Many clinical studies have demonstrated the dosimetric importance of applying such algorithms, in comparison with the convolution algorithms using point and pencil kernels. Clinical sites with significant tissue heterogeneity, such as lung, nasopharynx/oropharynx and esophagus, especially stand to benefit from these advanced algorithms.

This session returns to the basics of the core engine of the external beam treatment planning system, namely dose calculation algorithms. Explanations of the commonly used current algorithms and their short comings as well as commissioning and QA will be visited.

Learning Objectives:
1. Understand of current state of commonly used external beam treatment planning algorithms.
2. Understand the clinical implementation process of treatment planning with the advanced algorithms.
