That should read 650 pixel slice with 720 projections is 1.25 seconds. The
time to reconstruct all 515 slices is 515*1.25 ~ 11 minutes. This is on a
dual 750 MHz Pentium system.

interesting page ! thanks for your help. Do you know anyone who is
developping reconstruction for cone beam geometry? In our lab we have
microtomography with cone-beam .
http://bofi87.df.unibo.it and http//webdida1.csr.unibo.it/pasini/tomografia

Thanks a lot
Alessandro
