Abstract
Spatially distinct Spectral Doppler information is displayed. A spectrum is determined for each of a plurality of spatial locations, such as associated with different receive beams. Given a plurality of spectra at different spatial locations, an image may be generated as a function of the spectra. For example, a two-dimensional image has display values for different pixels or locations derived from one or more characteristics of the spectra, such as the maximum velocity with energy above a threshold for each location. As another example, the spectrum from the set of spectra with the highest maximum velocity is selected for generating a spectral strip display.
