摘要： Beamforming to image an object (310), such as an interventional tool, is enhanced by initializing the beamformer (308) with the object's location, and optionally its orientation. The initializing uses an estimate of the location/orientation. The estimate is derived from the output of one or more sensors (304, 306). These are disposed external to the imaging array (316) that operates with the beamformer. The estimate is made without the need for a result of any imaging based on data arriving by reflected ultrasound. One or more of the sensors may be attached to the object, which may be elongated, as in the case of a needle or catheter used in medical diagnosis and treatment. In some implementations, one or more of the sensors are attached to the imaging probe (302). The sensors may be, for example, ultrasound, electromagnetic, optical, or shape sensors. Alternatively, ultrasound transmitting transducers may be substituted for the ultrasound sensors.

摘要： An ultrasonic diagnostic imaging system produces an image with an extended focal range by transmitting a plurality of beams spaced along an array for multiline reception. The receive multilines of a plurality of transmit beams are spatially aligned and are combined with phase adjustment between the respective receive multilines to prevent undesired phase cancellation. The combined multilines produce the effect of an extended transmit focus so that an image produced using the combined multilines exhibits an extended focal range. To prevent motion artifacts the multiline order is adjustable as a function of image motion.

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： An ultrasonic diagnostic imaging system produces an image with an extended focal range and reduced speckle by transmitting a plurality of beams spaced along an array for multiline reception. The receive multilines of a plurality of transmit beams are spatially aligned with phase adjustment between the respective receive multilines to effect signal alignment, detected and combined. The combined multilines produce the effect of an extended transmit focus so that an image produced using the combined multilines exhibits an extended focal range. Speckle is reduced by nonlinearly combining received multilines produced by different transmit apertures.

摘要： The present invention relates to a method for producing an ultrasound image with a variable refractive lens (6) by transmitting a plurality of transmit beams (Txl-Tx4) from an array of transducers (5) and receiving echo signals with the array of transducers (5) through the variable refractive lens (6) with an associated lens shape. By combining echo signals of receive lines from different transmit beams which are spatially related, the invention enable producing an image using image data. The invention is beneficial for high frequency ultrasonic imaging with the transducers being relatively larger sized than hitherto needed for high frequency applications. The array of transducers does not need to be "well- sampled"; i.e. having the width or size being comparably to the center wavelength of the ultrasonic signals to be received. This is particularly important at very high frequencies where well- sampled arrays would require very small elements that would be very challenging to manufacture.
摘要翻译：本发明涉及通过从传感器阵列（5）发送多个发射波束（Tx1-Tx4）并用换能器阵列（5）接收回波信号来产生具有可变折射透镜（6）的超声波图像的方法， 5）通过具有相关镜片形状的可变折射透镜（6）。通过组合来自与空间相关的不同发射波束的接收线路的回波信号，本发明能够使用图像数据产生图像。本发明对于高频超声波成像是有益的，其中传感器的尺寸比迄今为止高频应用所需的尺寸相对更大。传感器阵列不需要进行“良好采样”; 即具有与待接收的超声波信号的中心波长相同的宽度或尺寸。这在非常高的频率下是特别重要的，其中采样阵列将需要非常小的元件，这对于制造将是非常具有挑战性的。

摘要： The weighted-average-based position (244) in the temporal domain is computed based on the sampling of shear wave displacement (226) along the propagation path. The weighting is, for example, by displacement observed at times (230) corresponding to sampling and represents the time of arrival of the shear wave at the shear-wave propagation path location being sampled. In some embodiments, the computed shear- wave times of arrival at respective locations are functionally related to known inter- location distances (250) to derive shear-wave group velocity. The derived velocity can serve as input into known algorithms for estimating shear elasticity of the medium, such as body tissue, for purposes of clinical diagnosis and therapy assessment.
摘要翻译：基于沿传播路径的剪切波位移（226）的采样来计算时域中的基于加权平均的位置（244）。例如，加权是通过在对应于采样的时间（230）处观察到的位移来表示的，并且表示剪切波在正被采样的剪切波传播路径位置处的到达时间。在一些实施例中，在各个位置处计算的剪切波到达时间在功能上与已知的位置间距离（250）相关以导出剪切波群速度。为了临床诊断和治疗评估的目的，导出的速度可以用作已知算法的输入，用于估计诸如身体组织之类的介质的剪切弹性。

摘要： An ultrasonic diagnostic imaging system transmits a plurality of focused beams normal to the plane of a transducer aperture and receives multiple receive lines in response to each transmitted beam. Sub-apertures of the transducer aperture are defined by apodization and signals of the sub-apertures are aligned and combined to produce signals exhibiting the effect of transmit steering at different angles with respect to the sub-apertures. The steered signals are detected and the detected signals relating to common points in an image field are combined. The combined detected signals are used to produce an ultrasound image with reduced speckle.
