An '''isocentric technique''' is where all beams used in a [[radiation therapy|radiation treatment]] have a common focus point, a.k.a. the [[isocenter]]. Isocentric techniques require less patient repositioning as multiple field arrangements can be delivered with gantry and collimator movements, reducing treatment times.<ref>{{cite book|last1=Mayles|first1=P.|last2=Nahum|first2=A.|last3=Rosenwald|first3=J.C.|title=Handbook of radiotherapy physics|date=2007|publisher=Taylor & Francis|location=Boca Raton|isbn=9781420012026|page=692}}</ref>
