The paper deals with the three-dimensional transmission tomography problem. The projection geometry with a source moving along a spiral is investigated. Three reconstruction algorithms are compared quantitatively. The main attention is paid to the comparison of the algorithms based on the equations of quasi-exact inversion with the approximate iterative method ART. The known algorithms are modified to be more stable with respect to noise. The recommendations how to choose an optimal algorithm for different projection schemes are proposed.
Keywords: spiral tomography, mathematical simulation.
