Dynamic conformal arcs are beams that use MLCs to shape the field to the selected target while the gantry delivers dose moving continuously around the patient. Utilizing a dynamic conformal arc with a typical 2D/3D beam arrangement can produce a more conformal plan and reduce the dose to normal tissues. 

Learner Outcomes:
1. Describe how DCA creates a more conformal dose distribution compared to AP/PA, opposed laterals, or other simple beam arrangements
2. Outline how to set fields and utilize dynamic conformal arcs in treatment planning
3. Discuss when this technique is most ideal and for which set of patients
