摘要： A device and a method for computing a weighted-average-based position of a shear wave in a temporal domain based on a sampling of shear wave displacements along a propagation path of the shear wave. The weighted-average-based position is, for example, by displacement observed at a plurality of times that correspond to sampling, and represents a time of arrival of the shear wave at a location being sampled along the propagation path. Further, times of arrival of the shear wave at respective locations along the propagation path are functionally related to known inter-location distances to derive shear-wave group velocity. The derived shear-wave group velocity serves as an input into algorithms for estimating a shear elasticity of a medium, such as a body tissue, for purposes of a clinical diagnosis and therapy assessment.

摘要： An ultrasonic diagnostic imaging system produces an image of shear wave velocities by transmitting push pulses to generate shear waves. A plurality of tracking lines are transmitted and echoes received by a focusing beamformer adjacent to the location of the push pulses. The tracking lines are sampled in a time-interleaved manner. The echo data acquired along each tracking line is processed to determine the time of peak tissue displacement caused by the shear waves at points along the tracking line, and the times of peaks at adjacent tracking lines compared to compute a local shear wave velocity. The resultant map of shear wave velocity values is color-coded and displayed over an anatomical image of the region of interest.

摘要： Shear wave dispersion ultrasound vibrometry (SDUV) is implemented in some embodiments to form, from a single tracking pulse, in-parallel-directed receive lines (411-426) for making measurements of a monochromatic shear wave. In some embodiments, sampling is performed, over spatial locations by means of passes over the locations, in an interlaced pattern (600) for making measurements of the wave. In some embodiments, measurements are made of the wave and to the measurements are applied a bank of filters (S724) that are tuned to respective candidate wave speeds, all without the need to determine a difference between wave phases at different spatial locations (451-454).

摘要： An invasive medical device includes a fluid path of microbubbles which is imaged by ultrasound during use of the device. The fluid path extends through the device, preferably to the distal end of the device, so that the diffuse reflection of ultrasound from the microbubbles can be received to image the location of the device. The fluid path can be open, terminating at the tip of the device, or can be a closed path of a circulating microbubble fluid used for imaging and/or cooling.

摘要： Searching multimedia information which allows determining preferences based on very little amounts of data. The preferences are nonparametrically determined. Each preference is quantized into one of a plurality of bins. By doing the quantization, the distances between positive and negative samples are increased. The quantization amount may change depending on the number of samples which are used. The quantization can be used in a support vector machine or the like.

摘要： A Discrete Fourier Transform watermark for use with digital images/video. A Y component of a Y, U(Cb), V(Cr) digital data stream representing color components of digital video is extracted as the digital data for embedding the watermark. The digital data is then scaled to a standard size. A Discrete Fourier Transform (DFT) is performed on the digital data, and a magnitude domain of the Discrete Fourier Transform is computed. The watermark is embedded into selected frequency bands of the computed magnitude domain of the Discrete Fourier Transform, thereby creating a watermarked magnitude domain. The selected frequency bands comprise one or more middle frequency bands, and the middle frequency bands comprise a band of circular rings of the magnitude domain. An inverse Discrete Fourier Transform is performed on the watermarked magnitude domain to reconstruct the digital data with the embedded watermark.

摘要： Methods and systems for measuring mechanical property of a vascular wall and a method and system for determining health of a vascular structure are provided wherein local deformation of a vessel wall resulting from physiologic pressures with altered transmural forces is measured. A non-invasive free-hand ultrasound scanning-procedure was performed to apply external force, comparable to the force generated in measuring a subject's blood pressure, to achieve higher strains by equalizing the internal arterial baseline pressure. When the applied pressure matched the internal baseline diastolic pressure, strain and strain rate increased by a factor of 10 over a cardiac cycle. Radial arterial strain was assessed in the vessel wall over the entire deformation procedure using a phase-sensitive, two-dimensional speckle-tracking algorithm. An elastic modulus reconstruction procedure was developed to estimate the non-linear elastic properties of the vascular wall.

摘要： An ultrasonic diagnostic imaging system for shear wave measurement transmits push pulses in the form of a sheet of energy. The sheet of energy produces a shear wavefront which is a plane wave, which does not suffer from the 1/R radial dissipation of push pulse force as does a conventional push pulse generated along a single push pulse vector. The sheet of energy can be planar, curved, or in some other two or three dimensional shape. A curved sheet of energy can produce a shear wave source which focuses into a thin line, which increases the resolution and sensitivity of the measuring techniques used to detect the shear wave effect.
