    Abstract: An ultrasound imaging system includes a processor circuit in communication with an ultrasound probe. The processor circuit receives, from the ultrasound probe, ultrasound data representative of an ultrasound beam imaging an anatomical structure. The processor circuit determines, based on the ultrasound data, a measured boundary of the anatomical structure. The measured boundary includes multiple locations. The processor circuit determines correction vectors corresponding to the locations of the measured boundary. A magnitude of a respective correction vector is based on a depth of a corresponding location relative to the ultrasound probe and/or an orientation of the measured boundary at the corresponding location relative to the ultrasound beam. The processor circuit applies the correction vectors to the locations of the measured boundary to determine a corrected boundary. The processor circuit outputs, to a display, an ultrasound image based on the ultrasound data. The ultrasound image includes the corrected boundary.

    Abstract: A method is provided for adapting a 3D field of view (FOV) in ultrasound data acquisition so as to minimize the FOV volume in a manner that is controlled and precise. The method comprises defining a volumetric region across which 3D ultrasound data is desired, and then adapting the data acquisition field of view (FOV) in dependence upon the defined volumetric region, to encompass the region. This is achieved based on adapting a scan line length (or scan depth) of each individual scan line based on the defined volumetric region. In some embodiments, the volumetric region may be defined based on anatomical segmentation of a reference ultrasound dataset acquired in an initial step, and setting the volumetric region in dependence upon boundaries of an identified object of interest. The volumetric region may in a subset of embodiments be set as the region occupied by a detected anatomical object of interest.

    Abstract: An ultrasound imaging system may acquire ultrasound data from a heart. The ultrasound data may be analyzed to on-invasively provide a value for cardiac pressure, such as left ventricular end diastolic pressure (LVEDP). In some examples, the ultrasound data may be acquired from B-mode images, Doppler images, and/or strain measurements. In some examples, the ultrasound data may be acquired across an entire cardiac cycle of the heart. In some examples, the ultrasound data may include strain measurements and/or volume measurements of the left atrium. In some examples, the ultrasound data may be analyzed by a correlation algorithm, such as a partial least squares model and/or a neural network.

    Abstract: A 3D ultrasonic diagnostic imaging system produces 3D display images at a 3D frame rate of display which is equal to the acquisition rate of a 3D image dataset. The volumetric region being imaged is sparsely sub-sampled by separated scanning beams. Spatial locations between the beams are filled in with interpolated values or interleaved with acquired data values from other 3D scanning intervals depending upon the existence of motion in the image field. A plurality of different beam scanning patterns are used, different ones of which have different spatial locations where beams are located and beams are omitted. In a preferred embodiment the determination of motion and the consequent decision to use interpolated or interleaved data for display is determined on a pixel-by-pixel basis.
