High-Frame-Rate Doppler Ultrasound Using a Repeated Transmit Sequence

The maximum detectable velocity of high-frame-rate color flow Doppler ultrasound is limited by the imaging frame rate when using coherent compounding techniques. Traditionally, high quality ultrasonic images are produced at a high frame rate via coherent compounding of steered plane wave reconstructions. However, this compounding operation results in an effective downsampling of the slow-time s...

Compact Beamformer Design with High Frame Rate for Ultrasound Imaging

In medical field, two-dimension ultrasound images are widely used in clinical diagnosis. Beamformer is critical in determining the complexity and performance of an ultrasound imaging system. Different from traditional means implemented with separated chips, a compact beamformer with 64 effective channels in a single moderate Field Programmable Gate Array has been presented in this paper. The co...

High Frame Rate 3-D Ultrasound Imaging Using Separable Beamforming

Recently, there has been great interest in 3-D ultrasound imaging, but power constraints have precluded practical implementation of high-resolution and highframe-rate 3-D ultrasound in handheld imaging platforms. In this paper, we propose a separable beamforming procedure for both 3-D synthetic aperture and plane wave systems that drastically reduces computational and hence power requirements. ...

High frame rate ultrasound imaging using parallel beamforming

The human heart contracts and relaxes approximately once each second. This isa complex process where different parts of the cardiac tissue contract and relax atdifferent times and at different rates. The accurate evaluation of this deformation withultrasound requires the use of a high frame rate. The frame rate of a conventionalultrasound image is limited by the round trip propa...

High-frame rate vector flow imaging of the carotid bifurcation

Carotid artery atherosclerotic disease is still a significant cause of cerebrovascular morbidity and mortality. A new angle-independent technique, measuring and visualizing blood flow velocities in all directions, called vector flow imaging (VFI) is becoming available from several vendors. VFI can provide more intuitive and quantitative imaging of vortex formation, which is not clearly distingu...
