Eclipse v18.0 is designed to meet the challenges of patient care today: to improve outcomes with more accurate techniques while relieving the strain on clinical resources. It provides several powerful features whose goal is to improve both precision and clinical efficiency today including SBRT NTO (a tool for normal tissue optimization for stereotactic body radiotherapy), Enhanced Leaf Modeling (ELM), and a new, intuitive way, to interact with dose via the Multi-Criteria Optimization (MCO) tool.
SBRT NTO
Clinics seeking to apply stereotactic accuracy to extracranial disease sites can create complex plans more quickly and easily with the automated SBRT NTO algorithms provided in Eclipse v18.0. SBRT NTO automates the process, eliminates time-consuming optimization steps, reduces error-prone manual contouring of optimization shells, and enforces sharp dose fall-off around target volumes to safeguard healthy tissues. SBRT NTO supports coplanar and noncoplanar techniques for extracranial disease sites, enabling flexible design of treatment plans aligned with each clinic’s expertise.
“SBRT NTO helped achieve highly conformal SBRT plan quality (controlling R50%) without needing to create tuning or ring structures and/or adjusting NTO conditions to spare the doses to nearby normal tissue.”

Enhanced leaf modeling (ELM)
Traditional multileaf collimator (MLC) modeling can result in cumbersome beam configuration workflows and challenges with treatment plan quality assurance. Eclipse v18.0 introduces ELM to overcome these challenges. It can help ensure precision for even the smallest of field sizes found in SRS and SBRT. Specifically, ELM improves the modeling of the leaf tip and screw cutout of the MLC, with one dosimetric leaf gap (DLG) for all energies.
MCO Isodose Line Dragging
In Eclipse v18.0, Multi-Criteria Optimization (MCO) has been enhanced to give planners more control over dose distribution. The Isodose Line Dragging feature allows planners to interact intuitively with isodose lines or the color wash to sculpt or adjust dose in real time.
“MCO Isodose Line Dragging has enabled our planners to make small modifications that can have a high clinical impact, by helping to reduce hot spots in critical OARs and refining the low dose bath associated with VMAT planning.”
