ERROR ANALYSIS OF TOMOGRAPHIC FILTERS .2. RESULTS

The convolution backprojection algorithm (CBP) has been studied from t he point-of-view of the already published error formula which relates the error in reconstructions, under certain ideal conditions, to the F ourier-space derivatives of the filter functions employed in CBP. The results, for simulated images representing a damaged nuclear reactor f uel assembly and a cross-section of human brain, indicate that the err or pattern obtained is in concurrence with the theory. Experimental re sults for a pixel size of 20 mum are also included.
