I have enjoyed the discussion about eliminating tattoos. My understanding is departments that are markerless do daily ConeBeam CT (CBCT) or kV imaging for geometric verification and correction.
We would like to go tattoo-less for breast patients. We are currently treat the majority of our breast patients (without nodal involvement) with tangential fields (whole-breast) and do MV portal imaging (first 5 fractions and then weekly if imaging is good).
With MV imaging we check Central Lung Distance (cm), Anterior Coverage (cm) and inferior Coverage (cm) and compare with DRR values.
Is it possible to get these values from ALignRT in order to compare if there is agreement between the deltas from ALignRT and our imaging system?
