Computation of functional angiographic images with the Hartley transform
L. Legrand, H. Diebold, A. J. Tosser, L Dusserre · 2003
The authors introduce the Hartley series and present the formulas for computing amplitude and phase images with the fast Hartley transform. This approach is then applied to image sequences digitized from conventional angiographic films. The computing times are roughly the same as with the fastest equivalent Fourier algorithms.>
