(a) A representation of for the projections whose azimuthal angle is shown in the x axis of the plot, for different numbers of projections involved in the algorithm. (b) A representation of the average (filled circle) and lowest (empty circle) values of the error metric as a function of the number of projections involved in the reconstruction. (c) A representation of the average with respect to the average relative angle in between projections involved in the reconstructions for three and four projections. |
