NEW! Segmentation Probability Variables for MRI in EnSight

Problem EnSight doesn’t have segmentation capability Creating Clip planes and calculating flow is hard in EnSight because the clip planes don’t move but the heart and blood vessels do. So EnSight is being used mostly only for visualization. EnSight data is being dumped to Matlab to make calculations that EnSight is perfectly capable of doing if there was segmentation information in EnSight. Solution: Use Mimics segmentation info in EnSight.

Velocity MRI Data Process Bring velocity data from MRI into EnSight MRI > Matlab/scripts > EnSight is the process for velocity data. Matlab/scripts come from Northwestern U., U of Wisconsin, Linkoping U., Stanford, U. C. San Francisco or other existing EnSight user base. EnSight Case File is produced which has volume and velocity variable. MRIMatlab Matlab Scripts EnSight

Improved MRI Data Process Bring segmentation from Mimics into EnSight MRI > Matlab/scripts > EnSight is already the process for velocity data. Probability of aorta, or other structure is an added variable to the EnSight files. MRIMimicsTranslatorEnSight

NEW! Segmentation Probability Variables for MRI in EnSight To make this image, 1)isosurfaced a field 2)changed the lighting to smooth 3) Use SmoothMesh() to generate a displacement map (this removes "mesh imprinting" artifacts).

What are these Variables? Segmentation Probabilities. Can be used for visualization or calculations Clips, Isosurfaces Calculations – Flow, etc

Static or Transient/Dynamic This process works for a single timestep or a transient timeset. So moving segmentation surfaces are not a problem and the probabilities update automatically over time.
