    Abstract: An imaging steering apparatus includes sensors and an imaging processor configured for: acquiring, via multiple ones of the sensors and from a current position (322), and current orientation (324), an image of an object of interest; based on a model, segmenting the acquired image; and determining, based on a result of the segmenting, a target position (318), and target orientation (320), with the target position and/or target orientation differing correspondingly from the current position and/or current orientation. An electronic steering parameter effective toward improving the current field of view may be computed, and a user may be provided instructional feedback (144) in navigating an imaging probe toward the improving. A robot can be configured for, automatically and without need for user intervention, imparting force (142) to the probe to move it responsive to the determination.

    Abstract: The invention provides a method for generating a compound ultrasound image. The method includes acquiring and beamforming channel data. Using the beamformed channel data a plurality of images, each image comprising a plurality of pixels, of a region of interest are obtained and an image information metric, wherein the image metric is associated with a pixel of the plurality of pixels, is assessed. The acquiring of the plurality of images and the assessment of the image metric are performed in parallel. For each image of the plurality of images: a per-pixel weighting for each pixel of the plurality of pixels based on the assessment of the image information metric is determined and applied to each pixel of the plurality of pixels. Finally a compound ultrasound image is generated based on the plurality of weighted pixels of the plurality of images.

    Abstract: Issuance of ultrasound pulses to a volume and receiving echo data is followed by estimating, based on the received data, center frequency subvolume-by-subvolume. Distinguishing between heart and lung tissue occurs based on a result of the estimating, and may include automatically identifying a spatial boundary (332) between the heart and lung tissue (324, 328), or a user display of center frequencies that allows for visual distinguishing. The issuance can include issuing, ray line by ray line, pair-wise identical, and/or pair-wise mutually inverted, ultrasound pulses. Center frequency calculations may be made for incremental sampling locations of respective imaging depth along each of the A-lines generated from echo data of the rays. The distinguishing might entail averaging center frequencies for locations along an A-line, and applying a central frequency threshold to the average. The leftmost of the qualifying A-lines, i.e., that meet the threshold, may determine the spatial boundary in the current imaging plane.

    Abstract: Based on anatomy recognition from three-dimensional live imaging of a volume, one or more portions (204, 208) of the volume are selected in real time. In further real time response, live imaging or the portion(s) is performed with a beam density (156) higher than that used in the volume imaging. The one or more portion may be one or more imaging plane selected for optimal orientation in making an anatomical measurement (424) or display. The recognition can be based on an anatomical model, such as a cardiac mesh model. The model may be pre-encoded with information that can be associated with image locations to provide the basis for portion selection, and for placement of indicia (416, 420, 432, 436) displayable for initiating measurement within an image provided by the live portion imaging. A single TEE or TTE imaging probe (112) may be used throughout. On request, periodically or based on detected motion of the probe with respect to the anatomy, the whole process can be re-executed, starting back from volume acquisition (S508).

    Abstract: In some embodiments, ultrasound receive beamforming yields beamformed samples, based upon which spatially intermediate pixels (232, 242, 244) are dynamically reconstructed. The samples have been correspondingly derived from acquisition through respectively different acoustic windows (218, 220). The reconstructing is further based on temporal weighting of the samples. In some embodiments, the sampling is via synchronized ultrasound phased-array data acquisition from a pair of side-by-side, spaced apart (211) acoustic windows respectively facing opposite sides of a central region (244) to be imaged. In particular, the pair is used interleavingly to dynamically scan jointly in a single lateral direction in imaging the region. The acquisition in the scan is, along a synchronization line (222) extending laterally across the region, monotonically progressive in that direction. Rotational scans respectively from the window pair are synchronizable into a composite scan of a moving object. The synchronization line (222) can be defined by the focuses of the transmits. The progression may strictly increase.
