    • An ultrasonic Doppler flow (i.e. blood) imaging and/or measuring system capable of adaptively suppressing stationary or slowly-moving non-flow (i.e. tissue) signals having variable spectra from recovered ultrasonic echoes. In accordance with the invention, the tissue signals are suppressed using a tissue rejection filter having an attenuation characteristic which is controllably shaped based upon measured estimates of at least one spectral characteristic of the tissue signals to be removed, thereby maximizing the rejection of tissue movement signals and minimizing undesired attenuation of the blood flow signals. In accordance with one embodiment of the invention, the tissue rejection filter is embodied as a complex notch filter for filtering the baseband components of the recovered ultrasonic echoes, which filter has a variable notch shape and position as adaptively determined in response to changes in estimates of the spectral components of the tissue signal portion of the recovered echoes.

    • An ultrasonic imaging system has a three-dimensional acoustic display. Beam-formed ultrasound scan signals are separated into channel signals and are then filtered using head-related transfer function (HRTF) filters. An HRTF is associated with each of several points in an interrogation region. A filter coefficient processor selects, for each channel signal, a set of HRTF filter parameters according to which sample volume the channel signal comes from. Each HRTF parameter set defines left-ear and right-ear response functions to a calibration sound generated at a calibration point in a calibration space; the calibration point itself corresponds to a predetermined position in the interrogation region. The HRTF-filtered channel signals are then combined into left and right audio output signals which drive left and right speakers that the user listens to while performing the ultrasound scan. The calibration points in the calibration space are mapped to respective reference sample volumes located in a predetermined ultrasonic interrogation region.

    • In accordance with the principles of the present invention, advantage is taken by the inventors of the fact that the speed of operation of the digital hardware in a digital beamformer can be reduced by providing, for example, multiple phases of the data signals and then processing the multi-phase data in N parallel summing paths. An interpolation-decimation filter receives the multi-phase data from the N parallel summing paths and provides at its output a signal having a reduced data rate (1/N). In accordance with this technique, the speed of operation of the individual digital circuits for forming the required beamforming delays is not increased as compared to conventional post-beamforming interpolation schemes, so that hereby the effective data rate is increased by a factor N and results in a decrease of the delay quantization error by a factor N. In accordance with the principles of the invention, the interpolation-decimation filter is incorporated into the beamformer at a most advantageous place. That is, it is incorporated into the beamformer processing after partial beamforming of a group of receive channels and before formation of the final beam. This approach allows the final beamforming to be simple and performed at a relatively low data rate and allows the higher rate signal processing to be confined to circuitry which may advantageously be on a single type of integrated circuit which is repetitively used in the beamformer.
    • 根据本发明的原理,发明人的优点是可以通过提供例如数据信号的多个相位然后处理来减少数字波束形成器中的数字硬件的操作速度 N个并行求和路径中的多相数据。 插值抽取滤波器从N个并行求和路径接收多相数据,并在其输出端提供具有降低的数据速率(1 / N)的信号。 根据这种技术,与传统的后波束成形插值方案相比,用于形成所需波束成形延迟的各个数字电路的操作速度没有增加,因此有效数据速率增加了因子N,并导致 延迟量化误差减小因子N.根据本发明的原理,内插抽取滤波器在最有利的地方并入波束形成器中。 也就是说,它在一组接收通道的部分波束形成之后并且在形成最终波束之前被并入到波束形成器处理中。 这种方法允许最终的波束成形简单并且以相对较低的数据速率执行,并且允许较高速率的信号处理被限制在有利地可以在波束形成器中重复使用的单一类型的集成电路上的电路。
