[Insight-users] Access voxel coordinates

[Luis Ibanez]

Gabriela,

You don't need to use ImageVoxel.

Please follow Charlotte's advice and use

     image->TransformIndexToPhysicalPoint( index, point )

You will find more information about this in the
ITK Software Guide

   http://www.itk.org/ItkSoftwareGuide.pdf

in the "Data Representation" chapter


Regards,


       Luis
