Cranial radiosurgery workflow

Simplify Complex Planning for Cranial Indications

Count on intelligent, automation-support planning

The cranial radiosurgery workflow simplifies complex planning routines for cranial indications, such as arteriovenous malformations (AVMs), pituitary adenomas and vestibular schwannomas. A dedicated 4Pi arc setup optimization and a VMAT algorithm designed for radiosurgery provide improved plan quality and MU efficiency at the same time.

Preparing for cranial planning

We’ve built automation into every step of the pre-planning workflow including image fusion, distortion correction, object outlining and segmentation. Save time with fast and easy-to-use tools, add consistency and gain confidence from the submillimetric accuracy you’ll achieve along the way.

Rigid and deformable co-registration

Elements Distortion Correction corrects patient-specific distortions by applying a deformable registration developed exclusively for the cranium that respects the anatomical ground truth.

Organ-at-risk segmentation

Elements Anatomical Mapping automates the time-consuming process of contouring organs at risk by efficiently, consistently and accurately registering datasets to a synthetic MRI based tissue model. The tissue model includes all organs at risk and more than 100 cranial structures.

3D target outlining

Elements SmartBrush defines volumes on just two slices. This application outlines cranial tumors quickly and easily on multiple modalities, minimizing intra- and inter-observer variability compared to manual outlining. Delineate the object on two slices, the volume is automatically generated and respective reports can be created.

Creating the dose plan with Elements Cranial SRS

The Elements Cranial SRS workflow is designed to create consistent, high-quality SRS plans easily and effectively for single cranial targets and enables protocol-based VMAT radiosurgery planning.

Patented 4Pi arc setup optimization

High plan quality is achieved with a 4Pi optimization algorithm and highly conformal dose using VMAT designed for SRS, avoiding critical structures while delivering the most efficient plan.

Unique 3D views

Dose interface and unique 3D views highlight the most relevant dose coverage metrics and allow a comprehensive assessment of dose distribution.

Robust dosimetric results

Minimized modulation balances MU efficiency with target coverage for robust dosimetric results and efficient delivery times. The adaptive dose grid automatically provides additional calculation points for small targets based on structure size.

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.
