In Silico Modeling of Neurovascular Bundle Stimulation in Sim4Life V7.0
I watched the video,but I could not understand how to create the model by 2D pictures.Who someone could tell me the detail steps?

Th movie shows different approaches

• segment the image in iSEG
• import the segmentation in Sim4Life as labelfield
• mesh the image (creates a 2d triangular mesh with patches per tissue region)
• extrude the patches to create a 3d unstructured mesh

Or:

• import the image in Sim4Life
• draw splines on the contours of tissue regions. The line will snap to the image entity. Make sure to close the loops.
• cover the loops (flat sheet per loop) (Wire Tools -> Cover Loops)
• select the cover loops and merge (Boolean -> Merge)
• convert to mesh (Mesh Tools -> To Mesh)
• remesh patches to have reasonable resolution (Remesh or Local Remesh)
• extrude (Mesh Tools -> Extrude)

@bryn Thank you very much.I had succeeded.
