Description
This article describes a new class of non-Fourier filter/convolving functions which has been proposed for the popular convolution back projection algorithm in computerized tomography. The convolver coefficients are evaluated directly by geometric considerations involved in the chord-segment inversion (CSI) algorithm. This CSI filter/convolving function is tested on simulated images representing density ranges encountered in damaged nuclear fuel bundles and two-phase steam-water flows
