This directory contains two sets of images.

cheapCT*.pgm are 60 slices of the reconstructed volume of a calf
spine.  The reconstruction was performed using filtered
backprojection. 

fluoro*.ppm are 96 fluoro images of the calf spine from which the
above 60-slice cheap CT volume is reconstructed. These fluoro images
were taken over a 190 degree field of view, approximately centered on
the spine.
