Cn-tf JdBit(0) JO In two spatial dimensions a simplified inversion formula has been derived in [11] that uses the Hilbert transform (Hr g)(r) - P.V. dr' := - lim fl('' ~ dr', re R. JRr-r' 7re-»o JR^c] r' The operator Hr is the convolution with 1 /(irr) in the distributional sense and satisfies (FHr)(/cr) = — i …
