Picture processing in computed tomography [PDF]

open access: yesAmerican Journal of Roentgenology, 1976
Using the EMI scanner system computer, picture processing of various kinds can be performed. Computer programs enabling analysis of regions of interest, subtraction, smoothing, and reconstruction in three dimensions have been designed; they are easy enough to be handled by the regular staff. The potential of the methods is illustrated.
