spine-dedicated segmentation, curvature correction and target definition

Automated functionalities enable effective and straightforward pre-planning for spinal radiosurgery with emphasis on shielding the critical spinal cord while tightly fitting a steep dose gradient around select segments of the vertebral body

Anatomical Mapping Based on Synthetic Tissue Model

elements Segmentation spine

Automatic segmentation of spinal anatomy fundamentally streamlines extracranial treatment planning and serves standardization. The segmentation and labeling of spinal structures enables automatic CTV calculation and preservation of critical structures.

  • Complete Anatomical Mapping based on Synthetic Tissue Model
  • The patented Synthetic Tissue Model considers the complete anatomical tissue environment in the complex extracranial region to enable robust registrations
  • Automatic segmentation and labeling of vertebrae
  • Automatic definition of organ at risk (OAR) structures like heart, kidneys, esophagus, etc.
  • 3D views allow easy user orientation 


Curvature Correction

Elements spine curvature correction

Multi-level vertebrae matching along the spine enables multi-modal contouring and CTV definition. Deformable co-registration is built on anatomical mapping, which provides fundamental understanding of deformable and non-deformable tissues.

  • Automatic Elastic Fusion tailored and validated for multi-level vertebrae co-registration
  • Applies individual fusions per vertebrae enabled by thorough tissue classification to prevent bone deformation
  • Matches MR-CT or CT-CT while compensating for different spine curvatures
  • Enables multi-modal tumor and OAR definitions


Automated Target Definition with SmartBrush Spine

Elements smartbrush spine

Elements SmartBrush Spine software consistently and rapidly creates target volumes for the Elements Spine SRS workflow.

  • Intuitive selection of affected vertebra in innovative 3D view
  • Spine region recognition and corresponding target definition template selection
  • Automated target definition based on International Spine Consortium Guidelines*
  • Direct segment adjustment on 3D spine sector visualization for CTV fine-tuning
  • Automatic definition of optimization planning structures (spinal cord and spinal canal OARs)
  • Consistent workflow supports established guidelines and promotes patient safety
