Recently, kernel methods for the recovery of a function from its spherical means in spherical acquisition geometry have been proposed. We present ecient algo- rithms for these formulas in the two- and three-dimensional case. Our scheme applies Fourier techniques for certain convolution type integrals and discretizes
