The multi-spectral Doppler in medical diagnostic ultrasound imaging
2012
Spatially individual spectral Doppler information is acquired (30). Spatially separate transmission beams are formed at a same time or in parallel (26). There are one or more receive beams are formed in response to each transmit beam (28), said samples are provided for a plurality of laterally remote locations. There is a spectrum for each of a plurality of spatial locations determined (30). In another approach, samples for different regions are captured at different times. Scanning for each region is interleaved (40), based on the anatomical process. Since the spectral estimate (30) based on a continuous time series of transmission and reception, the scanning of a region is carried out for a time sufficient to spectral before scanning another area is performed. Taking advantage of the anatomical process time for the spectral (30) providing sufficient. Due to an anatomical process different regions to be associated with a river at different times.
