Since changes in tumor size during the course of treatments can have dosemitric impact, advanced radiotherapy protocols that utilize IMRT and IGRT increase the need for periodic plan adaptation.
iPlan® RT Adaptive automatically facilitates efficient, intuitive plan updates based on periodic CT scans prompted by physiological or anatomical changes of the patient, making adaptive radiotherapy both clinically and financially feasible.
- Advanced image fusion of initial CT and volumetric data generated during course of treatment from Cone Beam CT (CBCT)
- Automatic organ at risk (OAR) definition with iPlan® RT Atlas Segmentation
- Fast PTV adaptation in 3D with iPlan RT Smart Shaper® object optimization
- Automated iPlan® RT Dose template plan update or DICOM RT export

Rigid vs. Elastic CBCT Mutual Information
Automatic Fusion to Treatment Planning CT |
Adaptive Radiotherapy–ART workflow support and image fusion registration for CBCT (Cone-Beam CT) data sets.
- Automatic contouring is performed on treatment planning CT and initial treatment plan is imported
- Periodic CBCT image is fused to the treatment planning CT in order to register the new IGRT information
- Correlates the acquired CBCT to the 3D space of the initial CT to identify potential treatment response

Elastic Fusion and Volumetric Overview
|
|
| Differential Analysis of Delivered Dos on elastically fused CBCT | With more knowledge available to identify and assess patient response to treatment, multiple views and analysis of automatic elastic fusion results give increased clinical confidence and detail.
- Automatic contour transfer from the treatment planning CT onto the CBCT or automatic segmentation on CBCT via elastic image fusion
- Volumetric changes displayed in multiple views offer both visual and graphical support
|
Adapts Plan to Current Clinical Situation
Combined views of the current clinical situation improve the potential to adapt to changing the patient’s response to therapy.
- Volume change analysis, dose coverage analysis for treatment targets and cumulative dose analysis for OARs provides convenient clinical overview
- Dose overlay onto new and original structures enable clinical decisions regarding continuation of treatment with existing plan, or new treatment planning CT
- Complete re-plan due to anatomical changes or amount of delivered dose to OARs for enhanced clinical outcome
