Eclipse™ Treatment Planning System

Eclipse™ Treatment Planning System features tools designed for creating treatment plans by using 3D modeling, treatment simulation, dose distribution calculation and verification. Eclipse supports external beam treatments with photon, proton, and electron beams, high-energy stereotactic treatments, and low-dose-rate brachytherapy treatments, as well as cobalt therapy.

With its intuitive interface, simplified data settings, and easy-to-use tools, Eclipse increases productivity at the clinic. Automated tools in Eclipse allow the creating, importing and optimizing plans not only for one specific treatment unit, but across the clinic’s multiple linear accelerators.

Two examples of Eclipse’s advanced functionalities are GPU-supported algorithms, which significantly speed up dose calculations, and Multi-Criteria Optimization (MCO), which lets clinicians explore different clinical criteria in treatment planning and quickly tailor the dose distribution to reach the perfect solution for each patient case.

Eclipse is a KLAS Category Leader in Software & Services 2019.
