When using surface image-guidance for breast radiation, how do you accommodate for changes in anatomy?

It depends on the timing (where they are in their treatment course). If there is a notable change, we will re-CT, especially for seroma shrinkage. Sometimes, if there is a discrepancy within the first couple of treatments, we will re-capture the surface-guided setup. There are some data present indi...

It is infrequent, more so in the era of oncoplastic surgery, but if it happens, it needs resimulation.

I shall resim if there is any change in the treatment volume.
