IMRT

Rotational IMRT techniques: Alternatives for the creation of initial guesses

+ dynamic conformal arc

+ using the projection of target volumes / organs at risk to the beam apertures (e.g. Elekta ERGO++) + translating a fluence profile into sliding-window segments and arranging them on an arc (Philips Pinnacle SmartArc, Elekta Monaco) + an iterative angular resolution refinement, starting from beam shapes at large angular intervals and interpolating them (Varian RapidArc)
