HYBRIDARC RADIO SURGERY TM HybridArc™ intelligently combines two proven, conformal treatment methods for radiosurgery with automated and optimized blending—in seconds—of modulated dynamic conformal arcs and discrete IMRT technology. CRANIAL Non-Coplanar Arcs Coplanar Arcs EXPANDED CAPABILITIES As part of the iPlan® family of planning and treatment software, HybridArc enables rotational volumetric dose shaping and streamlines both simple and complex treatment planning. Flexible integration makes HybridArc ideal for both the latest advancements in linac technology, as well as established linear accelerators.* With zero-downtime installation and licensing flexibility, HybridArc authorizes multiple linacs to perform optimized volumetric arc therapies with straightforward implementation and quality assurance. DUAL STAGE OPTIMIZATION Increases target dose homogeneity and at-risk organ protection through arc and beam fluence optimization Streamlines integration of dose-constraint penalization and automated leaf sequencing Flexibly weights arcs and beams for optimized coplanar and non-coplanar arc dose delivery Shapes dose for concave regions and large structures through discrete dose painting capability Automates selection of arc quantity and length and IMRT beam quantity for immediate results * Requires linac with dynamic arc and IMRT capabili

CLINICAL POSSIBILITIES SRS Planning: Spine Metastasis Functional SRT Planning: Acoustic Neuroma Designed for accurate dose calculations for small fields and optimized for treatments performed in one-to-five fractions, HybridArc maximizes target dose conformity while minimizing exposure to normal tissue. HybridArc benefits from the strengths of DPL (Dynamically Penalized Likelihood) algorithm, one of the fastest optimization methods available, to optimize both the arc component and IMRT fluences. Depending on case complexity, the result is either a variation of enhanced Dynamic Conformal Arc (eDCA)...
