The inverse Radon transform was numerically simulated with a double-pole field(DPF).A DPF was reconstructed with algebraic reconstruction technique(ART) by iterating 500 times.As a result,the iteration converged throughout.The reconstructed field was similar to the model one in respect of position,pointing and shape of the peaks,but each peak was shorter than that of the corresponding one in model field.The borderline of reconstructed field showed an obvious fluctuation.Compared with the reconstructed single-pole(SPF),each of the three errors of the reconstructed DPF was bigger than the corresponding one of reconstructed SPF by mean-square error(MSE) at magnitude 10~(-4),absolte value error(AVE) and peak error(PE) at 10~(-3) and 10~(-2),respectively.Under the same condition,the reconstructed DPF had poorer precision than SPF.
