<p>Hello Kajal,</p>
<p>F.O.V variables are arbitrary computed as <i>scanner_radius(mm)</i><i>/4</i>
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.<br>
</p>
<p>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 (<i>-dim</i> for number of voxels,
<i>-fov /-vox</i> for field of view and voxel dimensions
initializations ).</p>
<p>Best regards,</p>
<p>Thibaut<br>

<div>Hello everyone,<br>
<br>
</div>
I am trying to create .geom file from a .mac file for PET
scanner system. In the .geom file created, I would like to know
how the voxels number transaxial, voxels number axial, field of
view transaxial, field of view axial are being calculated.<br>
