[IGSTK-Users] Question on Mesh representation

[Patrick Cheng]

Hi Ofer and Yoav,

1. You might find this thread in Insight-User list very helpful.

2. If the mesh is being given in the image coordinate system, then the 
image slice should overlaid with mesh. When you segmented the image to 
get the mesh, did you use the physical point (take origin and spacing of 
the image into consideration)?
