  • Patent number: 11134916
    Abstract: The invention relates to an ultrasound system (100) for sequentially performing a predetermined procedure for each of at least one region of interest. The ultrasound system (100) comprises an ultrasound probe (101) configured to transmit a first ultrasound signal (SG1) towards a region of interest and receive echo signals from the region of interest. The ultrasound system (100) also comprises a motion sensor (102) configured to detect a motion of the ultrasound probe (101) and generate a motion signal (MS) for indicating the motion of the ultrasound probe (101). The ultrasound system (100) also comprises a processor (103) configured to perform a predetermined procedure for a region of interest on the basis of the echo signals received from the region of interest if the motion signal (MS) indicates that the ultrasound probe (101) is stationary. The invention also relates to a corresponding ultrasound method.

  • Publication number: 20210298715
    Abstract: Systems, devices, and methods for automated, fast lung pulse detection are provided. In an embodiment, a system for detecting pneumothorax (PTX) includes an ultrasound probe in communication with a processor. The processor is configured to generate, using the ultrasound imaging data received from the ultrasound probe, an M-mode image including a pleural line of the lung. Using the M-mode image, the processor generates a difference image comprising a plurality of difference lines generated by subtracting adjacent samples of the M-mode image. The processor analyzes the difference image to determine whether the difference image includes a periodic signal corresponding to the heartbeat of the patient and outputs a graphical representation of detecting the lung pulse based on determining that the difference image includes the periodic signal corresponding to the heartbeat.

  • Patent number: 10939894
    Abstract: Ultrasound-based acoustic streaming for deciding whether material is fluid is dependent upon any one or more of a variety of criteria. Examples are displacement, speed, temporal or spatial flow variance, progressive decorrelation, slope or straightness of accumulated signal to background comparisons over time, and relative displacement to adjacent soft tissue. Echogenicity-based area identification is combinable with the above movement characteristic detection in the deciding. Fluid pool identification is performable from the area-limited acoustic streaming testing and ultrasound attenuation readings. Candidates from among the areas are screenable based on specific shapes or bodily organs detected. Natural flow can be excluded from streaming detection by identification of blood vessels. Processing for each FAST ultrasound view, or for the entire procedure, is performable automatically, without need for user intervention or with user intervention to identify suspected areas.

  • Publication number: 20200237337
    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 ā€œVā€ 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.

  • Publication number: 20200229798
    Abstract: An ultrasound system and method enable ultrasonic imaging by inexperienced personnel at the home of a patient under the guidance of a remotely located diagnostic imaging expert. Improper use of the scanning device is prevented by allowing the remotely located imaging expert to enable or disable the transmission of ultrasound energy by the ultrasound system. Other functions of the ultrasound system may also be controlled by the remotely located expert, such as determining whether acquired ultrasound images can be viewed locally on the ultrasound system.
