Spine metastases workflow
Spare the Spinal Cord with Steep Dose Falloff
Opt for automation to support spinal cord sparing
This automation-supported workflow is optimized for the treatment of spinal metastases and produces very steep dose falloff between the target and the spinal cord. The workflow ensures enhanced spinal cord sparing and offers automatic CTV and OAR proposals in line with the International Spine Consortium Guidelines.

Preparing for spine metastases planning
We’ve built automation into every step of the pre-planning workflow including anatomical mapping, curvature correction and target definition. Save time with fast and easy-to-use tools, add consistency and gain confidence from the submillimetric accuracy you’ll achieve along the way.
Compensating for spine curvature variations
Variations in the position of the patient in different scans can prevent accurate image fusion. The unique algorithm of Elements Spine Curvature Correction combines information from the Brainlab internal tissue classification to account for rigidity and deformability of different tissue types which is then used to highlight and correct deviations in spinal curvatures.
Accurately segmenting spinal anatomy
Curvature corrected, fused images are essential to establishing a solid foundation for segmentation. Automatic segmentation of spinal anatomy with Elements Anatomical Mapping uses our patented synthetic tissue model to identify and label the individual levels of the spine. Easy metal implant contouring and the use of material-specific electron density enable highly accurate Pencil Beam and Monte Carlo dose calculation1. This software fundamentally streamlines extracranial treatment planning and supports standardization.
Delineating spine metastases
The fused and segmented image can now be used as the basis of spine metastases delineation. Elements SmartBrush Spine SRS provides spinal tumor outlining tools for GTV contouring and automatically proposes the corresponding CTV and the cropped spinal canal object based on International Consortium Guidelines.
Creating the dose plan with Elements Spine SRS
Elements Spine SRS software is an automation-supported treatment planning software, optimized for the creation of high-quality spine metastases dose plans.
High-quality VMAT planning designed for spine radiosurgery
This automatic spinal VMAT algorithm can achieve superior plans in terms of gradient index for better dose fall-off, conformity index and spinal cord sparing.
Highly precise beam modeling and dose calculation
By using Brainlab reference beam models, the measurements for the highly accurate Monte Carlo dose calculation algorithm are reduced by 90% for all TrueBeam platforms with HD120 or Millenium MLC with 6MV and 10MV, standard and FFF mode.
