Abstract
A dual mode color Doppler imaging system using a linear array of transducer elements generates and transmits into an organism, such as the human body, an acoustic imaging beam optimized for B-mode imaging and a separate acoustic Doppler beam which is steered at preselected angles relative to the imaging beam and is optimized for Doppler data acquisition. Acoustic imaging echoes are acquired and displayed as a B-mode gray-scale image. Doppler data are acquired from multiple sample volumes along the direction of each Doppler beam. The Doppler information acquired along multiple lines is displayed as a color-encoded image that is spatially coordinated with, superimposed upon and simultaneously displayed with, the B-mode gray-scale image.
