the present invention relates to a method and system for distributed computing an s transform dataset of multidimensional image data of an object . the multidimensional image data are fast fourier transformed into fourier domain producing a fourier spectrum . the respective fourier frequencies are then partitioned into a plurality of portions of frequencies for simultaneously processing . processing of each of the plurality of portions of the fourier frequencies is assigned to a respective processor of a plurality of processors . the fourier spectrum of multidimensional image data and each of the plurality of portions of the fourier frequencies is transmitted to the respective processor . the portions of the fourier frequencies are then simultaneously processed in order to produce the s transform dataset . the s transform data are then collected and stored . the method and system for computing the s transform according to the invention provides a substantially increased computation speed enabling use of the s transform for practical applications in a clinical setting .
