  • Patent number: 12207917
    Abstract: The present disclosure describes imaging systems configured to generate adaptive scanning protocols based on anatomical features and conditions identified during a prenatal scan of an object. Systems may include an ultrasound transducer configured to acquire echo signals responsive to ultrasound pulses transmitted toward a target region. Processors coupled with the transducer can generate an image frame from the echoes and provide the image frame to a first neural network. The first neural network may be configured to identify an anatomical feature in the image frame. An indication of the anatomical feature may be provided a second neural network. The second neural network may then determine an anatomical measurement to be obtained based, in part, on the feature identified. The processors may be further configured to cause an indicator of the anatomical measurement to be obtained to be displayed on a user interface.

  • Patent number: 12193880
    Abstract: The present disclosure describes ultrasound systems configured to perform microbubble-based contrast imaging with enhanced sensitivity. The systems can enhance echo signals derived from microbubbles while suppressing echo signals derived from tissue by detecting phase shifts exhibited by microbubbles in resonance. To detect the phase shifts, and thereby distinguish between microbubble-based signals and tissue-based signals, the systems can transmit a series of ultrasound pulses into a target region in accordance with a predefined sequence. The sequence can include an initiation pulse configured to stimulate microbubbles into nonlinear oscillation, a detection pulse configured to detect the nonlinear oscillation, and a summation pulse formed by transmitting an initiation pulse and detection pulse with a small time delay therebetween.

  • Patent number: 12178654
    Abstract: An ultrasound system produces maps of acoustic attenuation coefficients from B mode image signals. A plurality of maps located in different parallel and elevationally separated planes (A, B, C, D, E) are produced, then compounded in the elevation direction. Confidence maps may also be produced for one or more attenuation coefficient maps, and the confidence map displayed or its measures used to determine weighting for the compounding process. The compounding of elevationally separate planes improves attenuation coefficient estimation in the presence of blood vessels affecting the estimates in one or more of the planes.

  • Publication number: 20240320598
    Abstract: A graphical ultrasound user evaluation tool is described. The evaluation tool employs a predictive model and log files recorded by the ultrasound scanner to determine one or more ultrasound user performance scores. The log files may be processed to extract actual (or recorded) performance metrics from the information (e.g., timed events such as button clicks) recorded in the log file, which are compared against predicted (or expected) metrics to determine the one or more performance scores. The predicted metrics may be obtained from a predictive model, which may be implemented by an analytical (e.g., regression or other) model or by a trained neural network. The ultrasound user performance scores are then graphically presented in a user-friendly manner, e.g., on a graphical dashboard which can provide a summary screen and further detailed reports or screens, responsive to user input, and/or update the scores based on comparison with a user-specified ultrasound user experience level.

  • Publication number: 20240315674
    Abstract: An ultrasonic diagnostic imaging system and method produce attenuation coefficient maps of a region of interest in an ultrasound image. In order to detect the presence of elevation aperture blockage, the system estimates attenuation coefficients by two different methods. The estimates produced by the two different methods are combined to produce a metric, which is evaluated as a function of depth. If the metric satisfies one or more criteria of measurement bias, elevation aperture blockage is identified and an alert of the blockage is produced for the user.
