Patient contouring
and plan evaluation
made easy

A comprehensive toolbox for physicians

Everything you need to efficiently represent the patient anatomy and easily compare and approve plans. If you are comparing RayStation with RayPlan you may want to check out Toolbox for physicians in RayStation also.

Segmentation the way it should be

RayPlan provides you with fast and user-friendly tools to efficiently and accurately contour the patient in the treatment planning process. Contouring OAR. It includes a comprehensive toolset ranging from manual tools to high-end semi-automatic and fully automatic contouring tools. Discover some of our customers’ favorite tools below.

Smart brush and smart interpolation
The image-guided smart brush and smart interpolation facilitate contouring by snapping to image features and can help delineate organs and targets using only a few contours. See video

 

Structure templates
Structure templates allow you to create ROIs with predefined name, type, and color which allows for consistently labeled structure sets according to the clinics’ protocol. Structure templates may also include geometries including density overrides for quick retrieval of support structures. 

ROI algebra
With ROI algebra, you can create derived ROIs using Boolean expressions and margins. A derived ROI remembers its expression and will automatically detect when it needs to be updated. Derived ROIs also goes into structure templates, saving you the time of specifying complex expressions.

“The automatic segmentation is a useful tool for handling the technical complexity of head and neck IMRT as well as the daily management of an important patient flow. In head-and-neck cancer, we have gained significantly for the contouring of healthy organs. We will soon begin using multi-atlas-based segmentation in our clinical routine for lymph node delineation.”

The UK’s Royal Marsden Hospital carried out an assessment of fully-automated atlas-based segmentation for a novel oral mucosal surface organ-at-risk. The center found negligible differences when comparing results for manual and fully automated segmentation, concluding that atlas-based segmentation is a suitable approach for this application. Read the study here.

“With more complex RT, delineation of organs at risk (OAR) has become a mandatory but also very time-consuming task for highly skilled staff. Multi-atlas segmentation in RayStation is a highly promising approach that can minimize the human resources needed for delineating OAR.”

Plan evaluation

Physicians can easily evaluate, compare and approve treatment plans.

The module is a comprehensive toolbox for evaluation and comparison of treatment plans and plan approval. From a number of predefined layouts, dose distribution, dose statistics, clinical goals and dose volume histograms of up to three different plans can be simultaneously compared. Dose can be directly computed on additional image sets for evaluation. For evaluation of robustness, dose can also be computed for a density perturbation or patient shift.
