Advanced Dose Calculation
Eclipse is an open, dynamic planning environment, continually advancing the speed and accuracy of dose calculation, and integrating new developments as they become clinically available. Eclipse integrates the optimum algorithm for different treatment modalities.
Fast AAA for calculating dose effects
Using photon scatter kernels in multiple lateral directions, the Anisotropic Analytical Algorithm (AAA) dose calculation accounts for tissue heterogeneity.
The Acuros XB advanced dose-calculation algorithm addresses two strategic needs of external-photon-beam planning: accuracy and speed. Acuros XB uses a sophisticated technique to solve the Linear Boltzmann transport equation, and directly accounts for the effects of heterogeneities in dose calculations.
Acuros® BV for brachytherapy
Acuros BV enables clinicians to rapidly calculate patient doses for brachytherapy treatments with a high level of accuracy and accounts for the dose effects from bone, tissue and air, as well as inserted applicators.
eMC for electron radiotherapy
The fast electron Monte Carlo (eMC) technique is based on the standard EGS4 Monte Carlo methods, but reduces the number of electron-transport steps through the patient. The eMC technique is comparable to the standard Monte Carlo simulation in terms of transportation accuracy.
Eclipse Registration and Smart Segmentation®
The Eclipse treatment-planning system helps to address the time-consuming and challenging aspect of treatment-planning contouring. Without going back and forth between standalone equipment, its integrated tools eliminate the non-value-added steps from the planning workflow.
SmartSegmentation knowledge-based contouring streamlines workflows, facilitating the definitions of the targets and at-risk organs in an efficient and consistent manner.
RapidArc® Radiotherapy Technology
RapidArc radiotherapy technology integrates seamlessly with Eclipse to enable clinicians to develop IMRT-quality treatments with a single arc—for a wide range of treatments. By combining the power of the Eclipse planning tools with the precision and speed of RapidArc, clinicians can develop highly individualised treatments with confidence.
Interactive IMRT Planning
Powerful 3D-conformal planning tools in Eclipse are combined with interactive dose-volume optimisation for fast, flexible and accurate Intensity-Modulated Radiation Therapy (IMRT) planning. Automatic optimisation of beam geometry simplifies the task of selecting the best beam angles for IMRT.
Clinicians can make real-time decisions using the interactive IMRT features in Eclipse. With thousands of patients at hundreds of institutions worldwide successfully treated with Eclipse-generated IMRT plans, it is an established solution for IMRT planning.
Using Eclipse to maximise collaboration, multi-disciplinary teams can work together easily and efficiently. Eclipse integrates the planning for frame or frameless immobilisation and intensity-modulated or cone-based treatments. This means that stereotactic treatments can be added to a clinician's portfolio of services without the need to learn another planning system. In Eclipse, interfaces for other radiation treatment-planning services are incorporated and use the same intuitive interface for stereotactic planning.
Dynamic Adaptive Radiation Therapy (DART) is a new, emerging capability that has the potential to improve clinical outcomes with relatively little effect on the current level of clinical productivity. In Varian's integrated oncology environment, all of the required parameters for patient treatment are immediately available to the electronic medical record (EMR) and treatment-delivery systems without importing or exporting. Eclipse can reconstruct dose distributions based upon CBCT images and the actual treatment parameters for DART.
Eclipse supports a variety of proton-beam lines as well as ocular planning. Eclipse proton planning combines the latest fast, accurate proton calculation algorithms with the power of the Eclipse treatment-planning system to create a single system for proton, photon, electron and brachytherapy planning. Proton plans can be combined and compared with other modalities, or used as the base dose for a boost.
BrachyVision™ works as a standalone brachytherapy treatment-planning system, or as part of an Eclipse treatment-planning system. For clinicians wishing to perform film-based brachytherapy planning, Eclipse includes BrachyVision 2D. Users requiring image-guided 3D brachytherapy planning require BrachyVision 3D. The BrachyVision treatment-planning system may be combined with the VariSource iX HDR afterloader and GammaMedPlus iX HDR/PDR afterloader.
