Image Registration Workspace

Rigid Registration

Register, Compare, and Transfer in one workspace

  • Automatic and manual rigid registration tools
  • Side-by-side display using a shared frame of reference
  • Supports CT, CBCT, MR, and PET/CT imaging
  • 4D CT image handling
  • ITV and PRV contour propagation
  • Structure transfer between registered image sets
  • Integrated structure comparison and analysis tools
  • DICOM and ESAPI interoperability

Deformable Registration

Review and Evaluate Deformation Results

  • Analyze transferred and deformed structures
  • Visualize deformation grids and heat maps
  • Compare original and deformed dose distributions
  • Transfer structures between registered image sets
  • Export registrations for connected workflows
  • Assessed deformed dose in a dedicated workspace

Re-irradiation Workflows / Adaptive Plan Sums

Align prior and current imaging to evaluate anatomical changes, transfer structures, and assess cumulative dose dose.

  • Multimodality for CT, MR, and CBCT support
  • Rigid and deformable anatomical registration
  • Structure transfer between registered image sets
  • Track anatomical changes across imaging time points
  • Export registrations to downstream applications
  • Create deformed plan sums in ClearCheck*
  • Calculate cumulative BED/EQD2 in ClearCheck*

* ClearCheck is required for deformed plan sums, cumulative dose assessment, and BED/EQD2 calculations.

“AutoContour’s deformed sum provides a more accurate representation during treatment courses requiring adaptive planning, such as head and neck cases, given significant changes in anatomy.”
Dr Alexander Diaz, Radiation Oncologist, Murray-Calloway County Hospital

of structures have a DSC > 0.9

Planning Structure Generation

Automatically transform newly created contours or incoming DICOM RT Structure Sets into plan-ready structures, reducing repetitive post-processing and improving consistency across patients and planners.

  • Zero-Click planning structure generation
  • Create margins, rings, crops, overlaps, and combinations
  • Use Boolean operations for precise modification
  • Remove small contour parts and fill holes with the new Clean operation
  • Refine contour boundaries with the new Smooth operation
  • Build reusable templates for consistent workflows
  • Utilize global and user-specific templates for added flexibility

Contour Review and Editing

Quickly navigate, review and refine contours with integrated tools designed for efficient editing.

  • Navigate grouped structures with automatic plane alignment and synchronized scrolling
  • Customize scroll speed, window/level, and zoom by structure
  • Manage slice intervals with configurable “Keep Every Nth Slice” controls
  • Edit with pencil, adaptive brush, interpolation, and multi-slice tools
  • Propagate adjustments across adjacent slices with Edit Assist
  • Switch automatically from the Brush to Eraser Mode for precise corrections

“Several features stand out across Radformation’s suite of tools. The brachial plexus contouring in AutoContour has been particularly valuable for ensuring accurate and efficient delineation.”

- Tosin Kayode, Director of Medical Dosimetry, Winship Cancer Institute.

“My everyday essentials are AutoContour, ClearCheck, and ClearCalc with RadMonteCarlo - they're absolutely central to how I work.”

- Michael Trager, Senior Radiation Physicist, Northwell Health

“With the volume of patients we treat daily, AutoContour significantly cuts down contouring time and improves consistency across patients”

- Nusirat Adeddewe, Medical Physicist, Medserve-Luth Cancer Center

“AutoContour is an intuitive and practical solution that was rapidly adopted due to its ease of use. It requires minimal post-processing, significantly reducing the time spent on manual contouring. Furthermore, the technology facilitates remote support for other units, ensuring a consistent standard of contouring across the network - even in high-demand or understaffed environments.”

- Rinette Koenig, Radiation Therapist, Icon Oncology, South Africa
