With the advancement of radiotherapy equipment, stereotactic radiotherapy (SRT) has been
increasingly used. Among the many radiotherapy devices, Halcyon shows promising …

Purpose To perform a comprehensive validation of plans generated on a preconfigured
Halcyon 2.0 with preloaded beam model, including evaluations of new features and …

The Halcyon is Varian's latest linear accelerator that offers a single 6X flattening-filter-free
beam with a jawless design that features a new dual layer multileaf collimator system with …

Abstract Machine learning (ML) methods have been implemented in radiotherapy to aid
virtual specific-plan verification protocols, predicting gamma passing rates (GPR) based on …

This study characterized the plan complexity of the dual-layer multi-leaf collimator (MLC)
performance for volumetric modulated arc therapy (VMAT) in Halcyon. Plan complexity …

This study evaluates the volumetric modulated arc therapy (VMAT) dosimetric comparison
between Halcyon ring gantry and TrueBeam c-arm linear accelerators for craniospinal …

Objective: High levels of beam modulation complexity (MC) and monitor units (MU) can
compromise the plan deliverability of intensity-modulated radiotherapy treatments. Our study …

Introduction The treatment fraction time is a key indicator of the external beam radiotherapy
process. The Halcyon system was designed to improve the clinical workflow, according to …

BACKGROUND Radiation therapy, especially the development of linear accelerators, plays
a key role in cancer management. The fast-rotating coplanar O-ring Halcyon Linac has …

Purpose Halcyon linear accelerators employ intensity‐modulated radiation therapy (IMRT)
and stereotactic body radiation therapy (SBRT) techniques. The Halcyon offers translational …
