Use? You mean currently? I thought they used cone beams, but I never worked on them directly...

A fan beam is ‘just’ a more collimated cone beam.

Yes, but this was only shown later -- The reconstruction algorithm for cone-beam was published in 1984 by research staff at Ford Motor Company. The Felkamp, Davis, and Kress algorithm was demonstrated as a natural extension of the fan-beam algorithm. -- first pencil beam, then fan-beam, finally cone-beam
