Abstract: The present disclosure describes an ultrasound imaging system configured to identify and display B-lines that may appear during ultrasound scanning of a chest region of a subject. In some examples, the system may include an ultrasound probe and at least two processors configured to generate a plurality of image frames from ultrasound echoes received at the probe. The processors may be further configured to identify a pleural line in each of the plurality of image frames, define a region of interest below each pleural line, identify one or more candidate B-lines within the region of interest, identify one or more B-lines by evaluating one or more parameters of each candidate B-line, and select a target image frame from the plurality of image frames by identifying an image frame that maximizes at least a number or an intensity of B-lines.

Abstract: The present disclosure describes an ultrasound imaging system configured to identify a target placement of an ultrasound probe for viewing a lung pleural line. In some examples, the system may include an ultrasound probe configured to receive ultrasound echoes from a subject to image a region of the subject and a data processor in communication with the ultrasound probe. The data processor may be configured to identify one or more candidate pleural lines and one or more A-lines corresponding to the candidate pleural lines, compute an A-line intensity of at least one of the A-lines, and apply the computed A-line intensity to indicate a target placement of the ultrasound probe for imaging the region for pleural line identification. The system may also include a user interface in communication with the data processor. The user interface may be configured to alert the user of the target placement of the ultrasound probe.

Abstract: The present invention proposes an ultrasound system and a method of detecting lung sliding on the basis of a temporal sequence of ultrasound data frames of a first region of interest. The first region of interest includes a pleural interface of a lung. A sub-region identifier (410) is configured to identify, for each of the ultrasound data frames, a sub-region of a scanned region of the ultrasound data frame, the sub-region comprising at least part of the pleural interface; a lung sliding detector (420) is configured to derive a parametric map for the sub-region on the basis of at least two ultrasound data frames of the temporal sequence, parametric values of the parametric map indicating a degree of tissue motion over the at least two ultrasound frames; wherein the lung sliding detector is further configured to extract data of the sub-regions from the at least two ultrasound data frames, and to derive the parametric map on the basis of the extracted data.

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.

Abstract: An embodiment of this invention provides an ultrasound device that assesses a bone of a subject in at least two modes comprising a first mode and a second mode. The ultrasound device comprises: a selecting unit configured to select a mode from the at least two modes; a first ultrasound probe configured to transmit an ultrasound signal to the bone; a second ultrasound probe configured to receive the ultrasound signal from the bone; an assessing unit configured to derive a first parameter of the bone based on the selected mode and the ultrasound signal received by the second ultrasound probe; and a coupler being configured to be switched to a first configuration in the first mode and to a second configuration in the second mode. The ultrasound probes are oriented in substantially a same direction in the first configuration, and in substantially an opposite direction in the second configuration.

Abstract: A system is for determining fat and lean body tissue components of body tissue. A propagating wave is provided into the body tissue. A first set of normally directed reflections of the propagating wave is received at a first measurement site and a second set of angled reflections of the propagating wave is received from the body tissue at a second measurement site. A fat body tissue depth and optionally also a lean body tissue depth are obtained based on the times at which reflections of the first and second sets are received. This arrangement requires only two receivers in order to resolve the depth of the fat and lean body tissue constituents. The propagation paths are simplified by arranging the transceiver to direct a wave normally into the tissue.

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 (230), 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 (210) are screenable based on specific shapes or bodily organs detected. Natural flow can be excluded from streaming detection by identification of blood vessels (206). Processing for each FAST ultrasound view (202), or for the entire procedure, is performable automatically, without need for user intervention or with user intervention to identify suspected areas.
