摘要： A method of full-field or “ping-based” Doppler ultrasound imaging allows for detection of Doppler signals indicating moving reflectors at any point in an imaging field without the need to predefine range gates. In various embodiments, such whole-field Doppler imaging methods may include transmitting a Doppler ping from a transmit aperture, receiving echoes of the Doppler ping with one or more separate receive apertures, detecting Doppler signals and determining the speed of moving reflectors. In some embodiments, the system also provides the ability to determine the direction of motion by solving a set of simultaneous equations based on echo data received by multiple receive apertures.

摘要： A system for detecting blood velocity within a blood vessel includes a piezoelectric transducer supported on a ceramic substrate. The ceramic substrate supports the piezoelectric transducer at a fixed angle of incidence that is greater than 0° and less than 90°. The ceramic substrate is formed of steatite ceramic and is configured to couple an ultrasonic signal emitted by the transducer to skin underlying the substrate.

摘要： The present disclosure provides an ultrasound flow imaging method and ultrasound imaging system. The system may include a probe, a transmitting circuit which may excite the probe to transmit volume ultrasound beams to the scanning target, a receiving circuit 4, and a beam forming unit which may receive the echoes of the volume ultrasound beams and obtain the volume ultrasound echo signals, a data processing unit which may obtain the flow velocity vector information of the target point in the scanning target and the three-dimensional ultrasound image data based on the volume ultrasound echo signals, and a stereoscopic display device which may display the three-dimensional ultrasound image data to form the spatial stereoscopic image of the scanning target and superimposes the flow velocity vector information in the spatial stereoscopic image.

摘要： A method for determining pressure gradients with ultrasound data includes acquiring ultrasound data of a vessel and generating a velocity vector profile for flow in the vessel with the ultrasound data. The method further includes computing an acceleration with the velocity vector profile. The acceleration includes at least a temporal acceleration, and computing the temporal acceleration includes reducing noise from the velocity vector profile and determining the temporal acceleration from the noise-reduced velocity data. The method further includes determining the pressure gradients with the computed acceleration. The method further includes displaying an ultrasound image of the vessel with indicia indicative of the pressure gradients superimposed thereover.

摘要： Velocities are volume rendered in ultrasound. Early ray termination is used to avoid compositing velocities of different signs together. As long as the velocities are of the same sign, compositing continues from the viewer to a back of the volume being rendered. Once the velocity changes sign, compositing is reduced or terminated to avoid compositing velocities of different directions. The velocity rendering emphasizes the velocities of one direction closest to the viewer.

摘要： Apparatus and methods for measuring and analyzing blood flow in vessels in the bodies of living subjects are provided. The true velocity vector, or a projection thereof onto a scan plane, for blood flowing at a location in a vessel is determined from multiple Doppler velocity components. The true velocity vector is displayed as a directional marker on an image comprising the vessel. The true velocity magnitude and angle, and scalar blood flow characteristics derived therefrom, are plotted as a functions of time and/or position across the depiction of the blood vessel in the image. Time intervals for which blood flow characteristic data is displayed and/or determined may be user configurable.
