When Adaptive Hybrid Surgery Analysis starts, it analyzes the data set you have chosen and calculates the outcomes of three potential radiotherapy plans. The calculation follows these steps:
Adaptive Hybrid Surgery Analysis adds a surface contour to the data set.
It analyzes the contents of the surface contour as an equivalent volume of water.
Using the outer contour, a water model is generated for dose calculation based on a Pencil Beam Algorithm using a homogeneous water equivalent electron density.
It calculates the effects on this volume for the three template treatment plans:
The potential effects of the three calculated treatment plans are shown for the selected tumor and each OAR in the data set.
