HIGH RESOLUTION TOMOGRAPHIC IMAGING METHOD

A method for use with a computerized axial tomographic scanner (CAT) of providing an image of a sample that has spatial resolution in the axial direction that is smaller than the width of the X-ray beam of the CAT. The sample is scanned at a plurality of points in a plurality of cross sections that are separated by a distance that is less than the width of the X-ray beam of the CAT to determine the measured density function for each of the plurality of points. The measured density function is deconvolved with the beam width function for the CAT for each of the plurality of points to obtain the actual density function for the plurality of points. The actual density function is then used to generate an image of the sample that has a spatial resolution in the axial direction that is smaller than the width of the X-ray beam of the CAT.
