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%.
