dear all,
 
these days i read a paper in insight journal, the title of this paper is "ITK-Based Implementation of Two-Projection 2D/3D Registration Method with an Application in Patient Setup for External Beam Radiotherapy "
 
and  i have a problem about this paper
 
in this paper, the author says that "To align a 3D image with our coordinate system, the user needs to provide the continuous voxel  indices of the isocenter  location with respect to the  image volume." so what should i do to get continuous voxel  indices of my C-arm  isocenter  location with respect to my CT image volume?
do i need to ask a doctor in hospital?
 
thank you in advence,
 
michael
