## What it is

The radiation oncologist's up-front planning work for a complicated course of radiotherapy: reviewing the diagnosis and imaging, defining the target and the nearby organs that must be spared, choosing beam arrangements, and setting the dose and how it will be divided over the course. Complex is the top tier of a three-level planning family - it applies when there are multiple treatment areas, tumors close to sensitive structures, or specialized beam shaping and shielding, as opposed to the simple and intermediate levels used for straightforward single-area cases. This is the physician's decision-making, done before any beam is turned on.
