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...
متن کاملHigh 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. ...
متن کاملCompact 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...
متن کاملHigh Frame-Rate Television
The frame and field rates that have been used for television since the 1930s cause problems for motion portrayal, which are increasingly evident on the large, high-resolution television displays that are now common. In this paper we report on a programme of experimental work that successfully demonstrated the advantages of higher frame rate capture and display as a means of improving the qualit...
متن کاملHigh-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...
