IMRT

Automated VMAT planning • Overlap volume histogram-driven automated planning optimization (Wu et al , 2012) • Purpose: to prospectively determine whether it can be introduced in the clinical workflow • 40 H&N SIB-IMRT consecutive pts, ; for each pt a fully automated plan (AP), was compared to the clinical plan (CP) used for the treatment. • The study would show the non-inferiority of APs with respect to PTC coverage and secondary organ sparing (parotid, brachial plexus, esophagus, larynx, inner ear, oral mucosa). • In APs, average doses to secondary organs were reduced by 1.16%, overall average PTV coverage was increased by 1.26%.
