Abstract: For a classification-dependent user interface in ultrasound imaging with an ultrasound scanner, the ultrasound scanner classifies a view represented in an image. The user interface changes according to the view, allowing one or a few user inputs to be used for different user options or behavior combinations appropriate for the classified anatomy. The context from imaging alters the behavior of a given user input element of the user interface.

Abstract: For quantification of blood flow by an ultrasound system, B-mode images generated with a multi-transmit, coherent image formation produce swirling or other speckle patterns in the blood regions. These patterns, as represented in specially formed B-mode images, are tracked over time to indicate two or three-dimensional velocity vectors of the blood at a B-mode resolution. Various visualizations may be provided at the same resolution, including the velocity flow field, flow direction, vorticity, vortex size, vortex shape, and/or divergence.

Abstract: By identifying locations of contrast agent response, an intensity-based metric of contrast agent signal is used to control a duration of microbubble destruction with a medical ultrasound scanner. Feedback from motion of the transducer may be used to indicate when a user perceives enough destruction. A combination of both an intensity-based metric and transducer motion may be used to control the duration of bursting.

Abstract: Using computer-assisted classification and/or computer-assisted segmentation with or without monitoring the field of view for change, the workflow for ultrasound imaging may be made more efficient. The classification and/or segmentation is used to perform a next act in the sequence of acts making up the ultrasound examination. Rather than requiring a user to determine the act and implement the act, the ultrasound scanner determines and implements the act based on the identification and/or location of an imaged object. For example, the identification of the object as a kidney using a machine-learnt classifier triggers a color flow scan, and the location of the object determines a placement for the color flow region of interest (ROI), avoiding the user having to perform the ROI initiation and/or placement and increasing workflow efficiency.

Abstract: Motion artifacts are suppressed for three-dimensional parametric ultrasound imaging. Motion tracking is performed so that the parameter values derived over time are based on return from the same locations. Distortion due to the scan pattern is accounted for in the results of the motion tracking, such as by re-sampling the results to deal with discontinuity in time between data from adjacent sub-volumes and/or by aligning the scan pattern based on a direction of motion.

Abstract: In multi-modality imaging fusion with ultrasound, one transducer is used for registering ultrasound scan data with scan data from another mode. This registration is used to then align scan data from a different ultrasound transducer with the scan data of the other mode. The alignment may account for differences in position sensing between the two transducers.

Abstract: In contrast agent imaging, a beamformer and transducer scan a region of a patient having contrast agents. A detector detects the contrast agents with at least two different contrast agent imaging techniques from ultrasound data resulting from the scanning. A processor compares responses of the contrast agents detected between the at least two different contrast agent imaging techniques and selects a relative contribution of the at least two different contrast agent imaging techniques. The selection is based on the comparing. Contrast agent imaging of the patient is performed using at least one of the contrast agent imaging techniques. The performance is based on the selected relative contribution.

Abstract: A Doppler gate is automatically positioned in spectral Doppler ultrasound imaging. Samples acquired for multiple PW Doppler gates are used for B-mode and/or F-mode detection over time without interleaving transmissions for the PW Doppler. The B-mode and/or F-mode information are used to track gate placement. Alternatively or additionally, characteristics spectra from different gate locations are used to select a gate location. Either tracking may be used to change the locations sampled and/or beam characteristics, such as centering the locations and beam focus on the selected gate location.
