Dual-gated volumetric modulated arc therapy [PDF]

Radiation Oncology, 2014
Gated Volumetric Modulated Arc Therapy (VMAT) is an emerging radiation therapy modality for treatment of tumors affected by respiratory motion. However, gating significantly prolongs the treatment time, as delivery is only activated during a single respiratory phase.

Craniospinal irradiation by volumetric modulated arc therapy technique on halcyon

Journal of Radiation and Cancer Research, 2022
Aims: Craniospinal irradiation (CSI) is a challenging task on halcyon due to its field size constraint (28 cm × 28 cm). CSI was planned by volumetric modulated arc therapy (VMAT) technique on Halcyon (6MV) linac with no junction shift with multiple arcs ...
