Description of broad-band pulsed Doppler ultrasound processing using the two-dimensional Fourier transform.
Considering data from a Doppler sample volume as a two-dimensional function of depth and time, the properties of its two-dimensional fast Fourier transform (2DFFT) are discussed. It is shown that the… Expand
