    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.

    Abstract: An ultrasound imaging system (1) comprises an ultrasound transducer array (100) comprising a plurality of ultrasound transducer tiles (101a-d), each of said tiles having an independently adjustable orientation such as to conform an ultrasound transmitting surface to a region of a body (50) including a foreign object such as a pacemaker, a stent, or an interventional tool (200). Using a known spatial arrangement of a plurality of features (201-204) of the foreign object (200), the respective ultrasound images generated by the ultrasound transducer tiles are registered in order to generate a composite image, in which the position and orientation of the foreign object in the individual images is superimposed. The position and orientation of an interventional tool may be determined for each image using object recognition algorithms or using acoustic feedback information provided by at least three ultrasound sensors (201-204) arranged in a known spatial arrangement on the interventional tool.

    Abstract: The invention provides methods and systems for generating an ultrasound image. In a method, the generation of an ultrasound image comprises: obtaining channel data, the channel data defining a set of imaged points; for each imaged point: isolating the channel data; performing a spectral estimation on the isolated channel data; and selectively attenuating the spectral estimation channel data, thereby generating filtered channel data; and summing the filtered channel data, thereby forming a filtered ultrasound image. In some examples, the method comprises aperture extrapolation. The aperture extrapolation improves the lateral resolution of the ultrasound image. In other examples, the method comprises transmit extrapolation. The transmit extrapolation improves the contrast of the image. In addition, the transmit extrapolation improves the frame rate and reduces the motion artifacts in the ultrasound image. In further examples, the aperture and transmit extrapolations may be combined.
