In vivo vector flow imaging with retrospective pulsed wave doppler

The use of parallel receive beamforming in conjunction with plane wave imaging resulted in a robust vector Doppler modality, applicable for a wide range of patients. A sufficient B-mode quality was maintained by adopting a packet based acquisition scheme with a separate setup for each modality. Retrospective Pulsed Wave (PW) Doppler based on the same recording was feasible, and when combined with the available vector flow information, calibrated velocity spectra could be generated from arbitrary points in the image. All together, the proposed approach may provide more efficient clinical tools for conventional vascular imaging, as well as quantitative information for research into new markers for cardiovascular diagnosis.
