[Insight-users] How to calculate distance between 2 points in millimeter

[Jon Haitz Legarreta]

Dear Cary,
ITK will give you the distance in image units, i.e. pixel/voxels. You
should ask your image object about its resolution (how many physical
distance units each pixel accounts for) and then do the conversion.

HTH,
JON HAITZ
