Drag and drop organ modeling for enhanced IGRT workflow

Automatic mapping aids contouring

Contouring of organs and anatomy can be time consuming.  Model Based Segmentation (MBS) makes it easier.


From a library of pre-defined 3D organ structures models, you just drag and drop anatomical templates onto patient image data.  MBS software then automatically adapts the shape to fit the patient’s organs.  This reduces the time it takes to manually draw contours. And your library grows as you add your own data. 


Customized organ models

In addition to pre-defined models, you can create customized organ models based on your regional, demographic or clinical practice specialties.


For one physician a contour of the heart may only include the ventricles, for another it may include all vessels. Physician preferences are recorded and these customized organ models can be recalled time and again – significantly reducing contouring time.


Quickly modify treatment

IGRT workflow is enhanced with MBS software by allowing clinicians to easily propagate organs to alternate 4D datasets to determine the extent of the tumor movement within the patient.  Based on the patient’s response, you can react quickly to modify the treatment plan.


MBS software is essential for efficient adaptive planning and offers the opportunity for your department to move beyond IGRT to IGART.


Features and Benefits

  • Realize more consistent and more accurate contouring with MBS
  • Load and adapt pre-defined organs from the organ library
  • Create your own organ models
  • Move, scale, rotate and edit organs in 3D
  • Propagate organs to multiple CT datasets
  • Adapt or edit organs using CT and/or MR datasets
