  • Patent number: 11191518
    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.

  • Patent number: 11185311
    Abstract: Extracorporeal motion (130) relative to a medical subject being imaged is detected, through the imaging or from motion detectors on the imaging probe, and either backed out of the medical images so that it can be determined whether lung sliding exists or measured to determine whether lung sliding detection is to be suspended due to excessive extracorporeal motion. Image sub-regions (164, 168) corresponding to respective ones of the images are selected for image-to-image comparison such that the selected sub-regions contain only body tissue that is, with respect to imaging depth in the acquiring of the images, shallower than an anatomical landmark within the images. Based on a result of the comparing, lung sliding detection that entails examining image data deeper than the landmark may be initialized.

  • 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: 20200359991
    Abstract: The present disclosure describes ultrasound imaging systems and methods configured to identify lung abnormalities by determining a uniformity characteristic of a region of interest within ultrasound image frames. Systems can include an ultrasound transducer configured to acquire echoes responsive to ultrasound pulses transmitted toward a pulmonary target region. A processor coupled with the transducer may be configured to generate an image frame from the acquired echoes and determine a uniformity characteristic of the region of interest below a pleural line in the image frame. The processor may also be configured to determine a presence or absence of a lung abnormality, e.g., lung consolidation, within the region of interest based on a value of the uniformity characteristic. If a lung abnormality has been determined to be present, the processor can generate an indicator of the same, which may be displayed on a user interface in communication with the processor.

  • Publication number: 20200352547
    Abstract: The present disclosure describes an ultrasound system configured to identify and evaluate B-lines that may appear during an ultrasound scan of a chest region of a subject. In some examples, the system may include an ultrasound transducer configured to acquire echo signals responsive to ultrasound pulses transmitted toward a target region comprising one or both lungs. The system can also include one or more processors communicatively coupled with the ultrasound transducer and configured to identify one or more B-lines within the target region during a scan thereof. Based on the identified B-lines, the processors can determine a severity value of the B-lines and a pulmonary diagnosis based on the severity value in substantially real time during the ultrasound scan. The diagnosis may embody a distinction between cardiogenic and non-cardiogenic pulmonary edema.

  • Patent number: 10762631
    Abstract: The present invention proposes an apparatus and method for characterizing a tissue in a first region of a subject. The apparatus comprises a receiving unit (210) for receiving ultrasound data of the tissue in the first region and ultrasound data of a predetermined target reference tissue of said subject; a deriving unit (220) for deriving a subject-specific model of the target reference tissue on the basis of the ultrasound data of the target reference tissue; and a characterizing unit (230) for determining a match between tissue in the first region and the target reference tissue on the basis of the subject-specific model and ultrasound data of the tissue in the first region. Unlike conventional tissue characterization based on a large cohort of patient data, the proposed subject-specific model is personalized for the specific subject without any generalization, resulting in higher sensitivity and/or accuracy.

  • Publication number: 20190336098
    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.
