摘要： A reconfigurable linear array of sensors (e.g., optical, thermal, pressure, ultrasonic). The reconfigurability allows the size and spacing of the sensor elements to be a function of the distance from the beam center. This feature improves performance for imaging systems having a limited channel count. The improved performance, for applications in which multiple transmit focal zones are employed, arises from the ability to adjust the aperture for a particular depth.

摘要： A method and an apparatus for dynamically optimizing the frame rate as a function of an estimate of the target motion. First, the target motion is estimated, and then this estimate is used to control the number of firings per frame and/or the degree of frame-averaging. Preferably, the motion of the target is estimated by measuring pixel brightness variations on a frame-to-frame, region-to-region or line-to-line basis. Then the degree of frame-averaging is adjusted as a function of the motion estimate. Alternatively, target motion can be estimated by calculating the Doppler signal. Other imaging parameters, such as number of transmit firings per frame, size of the transmit aperture, and transmit excitation frequency, can be adjusted as a function of estimated target motion.

摘要： A method and an apparatus for adaptively suppressing incoherent data in a coherent imaging system. A focused ultrasound beam is transmitted with conventional transmit beamforming time delays. The returning echo signals are processed along two separate receive signal processing paths. The time delays along one processing path are set for traditional coherent receive beamforming, while the time delays along the other processing path are set to apply incoherent summing to the same set of return signals (e.g., time delays equal to zero). Then at each point in the receive beam or vector, the coherent and incoherent summation signals are compared. If the coherent and incoherent summation signals are of like amplitude, the beamformed signal of the first processing path is deemed incoherent, and its display is suppressed in the final image.
摘要翻译：一种用于在相干成像系统中自适应地抑制非相干数据的方法和装置。聚焦超声波束是用传统的发射波束形成时间延迟传输的。返回的回波信号沿着两个分开的接收信号处理路径被处理。沿着一个处理路径的时间延迟被设置用于传统的相干接收波束形成，而沿其他处理路径的时间延迟被设置为对同一组返回信号（例如，等于零的时间延迟）应用非相干相加。然后在接收波束或向量的每个点处，比较相干和非相干求和信号。如果相干和非相干求和信号的幅度相似，则第一处理路径的波束形成信号被认为是不相干的，并且在最终图像中抑制其显示。
