Abstract
An ultrasound imaging method and system includes a two-dimensional array transducer scanhead coupled to a beamformer. The beamformer and scanhead obtain signals corresponding to ultrasound echoes reflected from a measurement volume extending across a blood vessel. The signals are processed by a Doppler processor to generate data corresponding to a three-dimensional Doppler image of blood flow velocity in the sample volume. The signals are also processed by a B-mode processor to generate data corresponding to a cross section through the vessel. An image processor transforms the data corresponding to the three-dimensional Doppler image to data corresponding to a projection of the three-dimensional Doppler image onto a plane. The image processor also combines the transformed Doppler data with the B-mode data to create a composite image. Volume flow rate can also be determined by integrating the flow velocity in the projection of the three-dimensional Doppler image.
