[Rtk-users] Reconstruction Volume.

[Simon Rit]

Hi,
The typical solution (e.g., in clincial scanners) is to reconstruct the
field-of-view of the scanner (every point in space that is seen by all
source positions) because you know this is the only area of space where
your reconstruction is going to be accurate. rtkfieldofview generates this
FOV.
