Automatic Doppler Gate Positioning in Spectral Doppler Sonography

摘要

A Doppler gate is automatically positioned in spectral Doppler sonography (38). (28) Samples captured for multiple PW Doppler gates are used for B-mode and / or F-mode detection (30, 46) over time without interleaving transmissions for the PW Doppler. The B-mode and / or F-mode information is used to track gate placement (38). Alternatively or additionally, parameter spectra from different gate positions are used to select a gate position (40). Both types of tracking (32) can be used to change (40) the scanned positions and / or beam characteristic, such as centering the positions and beam focus on the selected gate position.
