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: An apparatus for use in analysing ultrasound image data of rectus abdominis muscles of a subject. The apparatus comprises a memory comprising instruction data representing a set of instructions, and a processor configured to communicate with the memory and to execute the set of instructions. The set of instructions, when executed by the processor, cause the processor to: obtain a sequence of ultrasound image data of the rectus abdominis muscles, the sequence of ultrasound image data having image data having been obtained using an ultrasound transducer tilted at different angles to the surface of the skin of the subject and thus having different angles of ingress of the ultrasound waves into the skin. The processor is further caused to select ultrasound image data from the sequence of ultrasound image data, the selected ultrasound image data comprising image data in the sequence in which a region of the rectus abdominis muscle appears clearest compared to other image data in the sequence of ultrasound image data, and make a measurement of the rectus abdominis muscles in the selected ultrasound image data.

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. Preferably, the subject-specific model of the target reference tissue is derived on the basis of both the ultrasound data of the target reference tissue and the ultrasound data of a background reference tissue of a different type than the target reference tissue.

Abstract: Guidance may be provided to users, at least in part, by graphic overlays on displays of ultrasound images. The guidance may assist users in acquiring images suitable for making hepato-renal index (HRI) measurements. In some examples, the guidance may assist the user in finding the proper imaging plane including a portion of the liver and kidney. In some examples, the guidance may further assist the user in proper placement of regions of interest within the image for calculating the HRI, such as at the same depth and appropriate portions of the liver and kidney. In some examples, one or more processors may analyze the image to ensure the quality is suitable for calculating the HRI.

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.
