A communal computing device, such as an interactive digital whiteboard, can become unlocked if a user is near the device. The communal computing device may use a sensor such as a camera to capture images of a person and obtain an identifier from a personal device such as a smartphone. A cloud-based provider that is trusted by both the communal computing device and the personal device may associate both the image and the identifier of the personal device with the same user identity. Obtaining the user identity from multiple, different sources provides a secure technique for the communal computing device to recognize a user without the user directly interacting with the communal computing device. If the sensor no longer detects the user or the personal device is no longer detected, then the communal computing device may log off the user. The personal device may be used to confirm log off.

An ultrasonic diagnostic imaging system acquires volume image flow data sets of subvolumes of a blood vessel over at least a cardiac cycle. Image data of the subvolumes is then aligned both spatially and temporally to produce 3D images of the volume flow of the blood vessel over a heart cycle. A volume flow profile curve is produced from the acquired volume image flow data sets. The subvolumes are scanned starting with the center of the blood vessel and proceeding outward therefrom. The blood vessel center may be designated manually by a user or automatically by the ultrasound system by Doppler or other methods. Each subvolume is scanned over a heart cycle, with the systolic phase in the temporal center of the acquisition interval. The subvolumes are scanned in synchronism with the heart cycle and the estimation of a heart cycle is updated during each subvolume data acquisition interval.

A system for visualization and quantification of ultrasound imaging data according to embodiments of the present disclosure may include a display unit, and a processor communicatively coupled to the display unit and to an ultrasound imaging apparatus for generating an image from ultrasound data representative of a bodily structure and fluid flowing within the bodily structure. The processor may be configured to estimate axial and lateral velocity components of the fluid flowing within the bodily structure, determine a plurality of flow directions within the image based on the axial and lateral velocity components, differentially encode the flow directions based on flow direction angle to generate a flow direction map, and cause the display unit to concurrently display the image including the bodily structure overlaid with the flow direction map.

In some examples, color Doppler data may be separated into luminance data and chrominance data. The luminance data may be modified without modifying the chrominance data. In some examples, the luminance data may be adjusted based, at least in part, on power Doppler data. The adjusted luminance data may be recombined with the chrominance data to provide augmented color Doppler data. In some examples, the power Doppler data may be enhanced by filtering, for example, by applying a Frangi vesselness filter, prior to being used to adjust the luminance data of the color Doppler data.

The present disclosure describes ultrasound systems configured to enhance flow imaging and analysis by adaptively adjusting one or more imaging parameters in response to acquired flow measurements. Example systems can include an ultrasound transducer and one or more processors. Using the system components, mean flow velocity magnitude and acceleration can be determined within a target region during an acquisition phase, which may include a cardiac cycle. One or more adjusted flow imaging parameters, such as adjusted ensemble length, temporal smoothing filter length and/or step size, can be determined based on the acquired flow measurements to increase the signal quality of newly acquired ultrasound echo signals. The adjusted flow imaging parameters can then be applied by the ultrasound transducer during a second acquisition phase.

A system for visualization and quantification of ultrasound imaging data may include a display unit, and a processor communicatively coupled to the display unit and to an ultrasound imaging apparatus for generating an image from ultrasound data representative of a bodily structure and fluid flowing within the bodily structure. The processor may be configured to generate vector field data corresponding to the fluid flow, wherein the vector field data comprises axial and lateral velocity components of the fluid, extract spatiotemporal information from the vector field data at one or more user-selected points within the image, and cause the display unit to concurrently display the spatiotemporal information at the one or more user-selected points with the image including a graphical representation of the vector field data overlaid on the image, wherein the spatiotemporal information includes at least one of a magnitude and an angle of the fluid flow.

An ultrasound system with a deep learning neural network feature is used to eliminate haze artifacts in B mode images of the carotid artery by analysis of orthogonal information. In a described implementation the orthogonal information comprises the structural information of a B mode image and motion information of the same field of view as that of the B mode image. In another embodiment the neural network reduces haze artifacts by reducing TGC gain at the depth of artifacts.
