Hello Kajal,

F.O.V variables are arbitrary computed as /scanner_radius(mm)///4/ for 
the transaxial component, and the axial dimension (mm) of the 
rsector/block for the axial component. The transaxial/axial number of 
voxels are calculated from these values in order to get (large) 
isotropic 4mm voxels.

The sole purpose of these variables is to be used as default for 
reconstruction dimensions/voxel sizes when using this scanner, in the 
case no dimensions have been initialized in command-line options. In 
practice, they are overwritten by the parameters entered in command line 
options (/-dim/ for number of voxels, /-fov /-vox/ for field of view and 
voxel dimensions initializations ).

Best regards,

Thibaut
