Early clinical experience with varian halcyon V2 linear accelerator: Dual‐isocenter IMRT planning and delivery with portal dosimetry for gynecological cancer treatments

Abstract

Halcyon 2.0 is effective to create complex extended-field IMRT plans using two isocenters with efficient delivery. Also Halcyon in vivo dosimetry is feasible for daily treatment monitoring for organ motion, internal or external anatomy, and body weight which could further lead to adaptive radiation therapy.
