What It Is

The Eclipse Treatment Planning System is a software platform designed for planning radiotherapy treatments. It allows clinicians to create precise treatment plans by integrating imaging data and optimizing radiation dose delivery to target tissues while sparing healthy tissues.

Clinical Applications

Common clinical scenarios for the Eclipse system include planning for whole brain radiotherapy, stereotactic body radiation therapy (SBRT), and adaptive radiotherapy. It is particularly useful in cases requiring precise dose delivery and sparing of critical structures.

Evidence Summary

The available literature includes 15 studies, comprising randomized controlled trials, prospective, and retrospective studies. These studies span from 2023 to 2025 and explore various applications of the Eclipse system in radiotherapy planning.

Reported Outcomes

Published studies report that the Eclipse system facilitates automated and adaptive radiotherapy planning, improving the accuracy of dose delivery and sparing of critical structures. It has been shown to be effective in planning for hippocampal sparing whole brain radiotherapy and cardiac-sparing accelerated partial breast irradiation.

Safety Profile

Reported complications include potential inaccuracies in image registration and contour propagation, which are critical for adaptive radiotherapy. However, no significant adverse events have been consistently reported across studies.

Evidence Limitations

Evidence gaps include a need for larger, long-term studies to validate the clinical outcomes and safety of the Eclipse system modifications. Some studies are limited by small sample sizes and retrospective designs.
