[Insight-users] pixels To cm..

[yasser salman]

Hi All,
i already segment a tumor region in 2D using
ConfidenceConnectedImageFilter and count the no of
pixels using RelabelComponentImageFilter , 
how can i convert these no of pixels into cm2 or mm2
(the corresponding area in cm or mm).
another question plz, if i run this program to a
volume, is the no of pixels in 3D (volume) equal to 
the sum of all pixels in segmented region in 2D
slices,

yasser
