Abstract: A puncture guiding apparatus includes a detector and processing circuitry. The detector is configured to detect passage of a puncture needle, the detector arranged in a vicinity of a living body contacting surface of an ultrasonic probe that is brought into contact with a living body. The processing circuitry is configured to output identification information for identifying a positional relationship between the puncture needle and a scanning plane of the ultrasonic probe based on a detection result obtained by the detector.

Abstract: Described here are systems and methods for monitoring airflow changes in a patient's airway during a medical procedure or as a general patient monitoring tool. Doppler ultrasound signals are acquired from an anatomical region within the patient's airway (e.g., a tracheal wall, a cricothyroid ligament, other connective or cartilaginous tissue within the trachea, larynx, or pharynx) and parameters from those Doppler ultrasound signals are compared to baseline parameters, which may include inputting Doppler ultrasound signals to a suitably trained deep learning model or other machine learning algorithm. When a threshold change is detected, an alarm can be provided to a user to indicate respiratory compromise and/or failure, which can include early airway compromise, airway failure, and/or airway obstruction.

Abstract: The present invention related to an ultrasound imaging system win which the scan head includes a beamformer circuit that performs far field subarray beamforming or includes a sparse array selecting circuit that actuates selected elements. When using a hierarchical two-stage or three-stage beamforming system, three dimensional ultrasound images can be generated in real-time. The invention further relates to flexible printed circuit boards in the probe head. The invention furthermore related to the use of coded or spread spectrum signaling in ultrasound imagining systems. Matched filters based on pulse compression using Golay code pairs improve the signal-to-noise ratio thus enabling third harmonic imaging with suppressed sidelobes. The system is suitable for 3D full volume cardiac imaging.

Abstract: Systems and methods of predicting future medical events are based on the processing of medical images. The prediction of premature birth and estimation of gestational age based on ultrasound images are presented as illustrative examples. The new abilities to estimate the probability of future medical events, before they otherwise could be predicted, provides new avenues for the development of preventative treatments.

Abstract: For ultrasound imaging with an ultrasound scanner, fat fraction of the tissue is measured. The fat fraction may be measured without access to channel data, such as from beamformed data. The speed of sound varies with the fat fraction of tissue, so the fat fraction is used to set the speed of sound in beamforming. Imaging the tissue using the fat fraction-based optimization for speed of sound may provide better images than imaging with an assumed speed.

Abstract: The disclosed non-invasive blood pressure systems and methods measure a patient's blood pressure without restricting blood flow. Other sensors, such as physiological sensors, sensors that sense data about the NIBP system components, and/or environment sensors sense data that is combined with the NIBP signal. The combined NIBP and sensor signals are used to measure a patient's non-invasive blood pressure.

Abstract: Non-invasive blood pressure (NIBP) systems and methods are disclosed that measure a blood pressure, and in some examples a beat-to-beat blood pressure, of a patient without restricting blood flow. The NIBP systems determine an efficacy of administered cardiopulmonary resuscitation (CPR) to the patient based on the measured blood pressure and are able to optionally output the CPR efficacy or generate user prompts based on the CPR efficacy. Further, the disclosed NIBP systems can generate user instructions to administer further treatment to the patient based on the CPR efficacy.
