    Abstract: Existing gas pocket detection approaches are based on visual observations of B-mode ultrasound images showing comparisons between normal soft tissue and gas pockets, which are time-consuming and dependent on operator experience. The present invention proposes an ultrasound system and a method of detecting a gas pocket. The ultrasound system comprises: an ultrasound probe (110) for transmitting an ultrasound signal toward the ROI and acquiring an ultrasound echo signal reflected from the ROI along a plurality of scanning lines; an obtaining unit (130) for obtaining a second harmonic component of the ultrasound echo signal for each depth of a plurality of depths along each scanning line of the plurality of scanning lines; and a deriving unit (140) for deriving a change in a center frequency of the second harmonic component along with the depth.

    Abstract: A medical ultrasound acquisition-data analysis device acquires channel data (144) via ultrasound received on the channels, uses the acquired channel data to estimate data coherence and derive dominance of an eigen-value of a channel covariance matrix and, based on the estimate and dominance, distinguishes microcalcifications (142) from background. Microcalcifications may then be made distinguishable visually on screen via highlighting, coloring, annotation, etc. The channel data operable upon by the estimating may have been subject to beamforming delays and may be summed in a beamforming procedure executed in the estimating. In the estimating and deriving, both field point-by-field point, multiple serial transmits (116, 118) may be used for each field point. In one embodiment results of the estimating and deriving are multiplied point-by-point and submitted to thresholding.

    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: A method for using an interactive visual guidance tool for an imaging acquisition and display system and configured for user navigation with respect to a blockage of a field of view detects, and spatially defines, the blockage. It also integrates, with the image for joint visualization, an indicium that visually represents the definition. The indicium is moved dynamically according to movement, relative to the blockage, of the field of view. The indicium can be shaped like a line segment, or two indicia can be joined in a “V” shape to frame a region of non-blockage. The defining may be based on determining whether ultrasound beams in respective directions are blocked. Included, for deriving the image, in some embodiments are imaging channels for receiving image data for which a metric of coherence, i.e., similarity among channel data, is computed. The determination for a direction is based on the metric for locations in that direction. One application is navigating an ultrasound probe between blocking ribs to achieve a standard cardiac view.

    Abstract: An interactive visual guidance tool for an imaging acquisition and display system and configured for user navigation with respect to a blockage of a field of view (216) detects, and spatially defines, the blockage. It also integrates, with the image for joint visualization, an indicium (244) that visually represents the definition. The indicium is moved dynamically according to movement, relative to the blockage, of the field of view. The indicium can be shaped like a line segment, or two indicia (244, 248) can be joined in a “V” shape to frame a region of non-blockage. The defining maybe based on determining whether ultrasound beams in respective directions are blocked. Included, for deriving the image, in some embodiments are imaging channels for receiving image data for which a metric of coherence, i.e., similarity among channel data, is computed. The determination for a direction is based on the metric for locations in that direction. One application is navigating an ultrasound probe between blocking ribs (208, 212) to achieve a standard cardiac view.
