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