摘要： Method and apparatus useful in the inspection of a target comprises scanning the target with a pulsed acoustic beam, sensing the pulsed beam after it has been modified by interaction with the target, producing a time-domain signal indicative of the modifications, processing the time-domain signal to produce a frequency domain representation of the modifications, and producing an image-wise display of the frequency domain representation of the modifications. In one execution disclosed, the frequency domain representation is altered and then reconverted to a time domain signal before display.

摘要： An ultrasound imaging system configured to simultaneously acquire and process multi-mode and multi-band echo information from a single set of pulse firings is provided. Raw ultrasound signals are digitized and stored in an I/Q data buffer. The stored data are then parallel preprocessed as a function of frequency band or alternative encoding. Parallel preprocessing optionally includes manipulating the data in respect to different imaging modes. Outputs of the parallel preprocessors are coupled to separate area formers used to simultaneously reconstruct various desired echo information to form a multi-mode or multi-band image. The echo formation process is optionally performed in parallel.

摘要： To improve real time 3D imaging performance, acquisition, beamforming, coherent image forming and/or image processing parameters are varied as a function of the viewing direction selected by the user. For example, the scan planes are oriented relative to the viewing direction. As a result rapid 3D rendering is provided without complex additional data interpolation or other 3D rendering processes. In another example, data along the lateral axis that is perpendicular to the viewing direction (i.e., display lateral axis) is acquired with parameters adapted to maximize field of view, detail and contrast resolution, while data along the lateral axis that is parallel to the viewing direction is acquired with compromised field of view, detail or contrast resolution. As a result, a high volume rate 3D imaging is achieved with 2D-equivalent detail resolution, contrast resolution and field of view along the display lateral axis.

摘要： Airports and other public places require security measures for the screening of human subjects for illicit objects and materials concealed from view beneath clothing. However, at present most of such screening processes involve only metal detectors, which are inherently incapable of detecting non-metallic illicit objects and materials. For this reason, there remains a strong need for novel systems and methods that can detect all types of materials. The present invention provides for a portal detection system that is configured for safe, rapid, and non-invasive scanning of human subjects. For this purpose, the portal detection system utilizes acoustic technology to achieve this end. The portal detection systems of the present invention may optionally be used in conjunction with conventional metal detection means. The invention encompasses portal detection systems, their use in scanning human subjects, and corresponding methods of scanning human subjects for illicit objects and substances.

摘要： Methods and systems for automatic adjustment of the transmit power are provided. Excess transmit power is determined as a function of the difference between a noise level and the lower end of the dynamic range of the system as configured. Based on the excess transmit power, the transmit power is reduced from the regulated maximum default settings to about a minimum while substantially preserving the original display image. This minimizes the acoustic energy delivered to the transducer and the body, thus reducing transducer heating and satisfying the FDA's ALARA principle.

摘要： A method and an apparatus for segmenting three-dimensional projected velocity images by limiting the volume of velocity data projected onto the imaging planes. If the volume of interest contains flowing blood, i.e., an artery or vein, the Doppler shift present in the ultrasound reflected from the flowing blood can be detected and then used to limit the amount of velocity data which is projected. Only pixels having velocity values within a predetermined range are projected onto the imaging plane.

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。

摘要： A method and an apparatus for tracking scan plane motion in free-hand three-dimensional ultrasound scanning using adaptive speckle correlation. The method employs a correlation index which adapts to different display dynamic range and post-processing filters. The method may include the following steps: choosing a kernel within each frame image for correlation calculations; rejecting duplicate image frames; measuring the degree of correlation between successive image frames; rejecting correlation estimates which may be associated with hand jitter and other artifacts; and computing the average frame-to-frame (i.e., interslice) spacing based on the average correlation estimate. This image-based motion tracking technique enables three-dimensional reconstruction with good geometric fidelity, without use of any external position-sensing device.
