Just wondering what everyone's filming protocols are for DIBH. How often are you filming and what images are you taking?

Imaging daily for all cases
2-field tangents MV before and during
3- field Ant KV (apply long and lateral shifts) + tangent MV (apply vertical shift only), if SCF is consistently off- CBCT is taken for dose calculation and assess if rescan +/-replan required.
