AN EXPERIMENTAL-STUDY OF CONTRAST RESOLUTION

Tomographic scanners are classified by various parameters, and two whi ch are important are the geometric resolution and the contrast resolut ion. A numerical study has been reported previously on the application of certain estimates of theoretical error in the tomographic inversio n formula. This study deals with the experimental aspects of those err or estimates, and further consolidates the findings of the previous wo rk in representing contrast by a mathematical quantity related to the object cross-section.
