A Flow Imaging and CW Spectral Analysis System by J. I. Mehi, Richard S.C. Cobbold, K.W. Johnston, C. Royer.
A system for Doppler ultrasound flow imaging and CW spectral analysis of the carotid artery is described. The uses a 24 element linear array with long axis aligned perpendicular to artery. Alteration aperture function allows either narrow beam be produced imaging, or as wide analysis. For by an eight crystal group swept across sequentially shifting along array. designed image line approximately 2 cm length. two-dimensional map blood projected onto plane surface skin obtained moving vessel using one-dimensional position sensor. mode operation middle twelve elements produce uniform 4 mm at depth cm. Initial results partially tested are described.KeywordsFlow ImagingField ProfileNarrow BeamSide Lobe LevelDoppler Flow ImageThese keywords were added machine not authors.
