Do you capture Cine MV imaging to verify the DIBH?

Cine imaging has been used previously but not since we moved to daily pre-tmt imaging.

we perform cine MV during the first fraction, since we have seen in a previous study that if the patient breath hold is reproducible and stable in the first fraction, it normally also is in the other fractions

all kV and MV images are done with DIBH

We shouldn’t over complicate everything. The dose has alway had variability along the chest wall with historically excellent results. What value are we adding to the patients outcome by using an mv cine daily?

We just do one field (Medial tangent) with "During" exposure at beginning of this field daily, so it is not truly cine for the entire treatment. We use OSMS/VisionRT for setup & monitoring, double-exposed MV ports initially then weekly.

Despite push-back from docs, you cannot bill for SGRT without performing KV first

We image the first three treatments. If setup based on imaging is outside the tolerance we will image daily.

BH-CBCT used to validate SGRT in the first 3fx and weekly thereafter

The lateral KVs verify the correct breath hold, and the gating system (Varian RPM) tracks stability of the DIBH.
