[ITK-users] 3D image centre

[D'Isidoro Fabio]

Hi,

since the image origin is defined in the middle of the "first" voxel and not at the very corner of the CT scan, I would calculate the image centre as:

               img_centre[0] = origin[0] + spacing[0] * static_cast<double>(size[0]) / 2.0 - spacing[0] / 2.;

Is that right?

Thank you
