A system for coherence imaging may receive ultrasound signals each having a respective delay associated with a respective ultrasonic transducer element in an ultrasonic transducer array. The system may obtain an approximation of the auto-correlation of ultrasound signals without any auto-correlation calculation, and determine the output image based on the approximation. In approximating the auto-correlation, the system may group the ultrasound signals into multiple portions, each corresponding to a respective sub-aperture of a plurality of sub-apertures of the ultrasonic transducer array. The system may determine a coherent sum of signals for each sub-aperture, perform a square operation or magnitude square operation over the coherent sum to obtain resulting data, normalize the resulting data, and sum the resulting data for all of the sub-apertures to generate the output image. A sub-aperture in the plurality of sub-apertures may overlap with another sub-aperture.

Methods and systems for coherence imaging in obtaining ultrasound images

An apparatus includes a processing device in operative communication with an ultrasound device. The processing device is configured to: receive a user selection of a lung imaging preset option and a user-selected imaging depth for the ultrasound device; define a threshold imaging depth based on a shallow lung imaging mode and a deep lung imaging mode (the threshold imaging depth is between approximately 4 cm and 8 cm); after receiving the user selection of the user-selected imaging depth, compare the user-selected imaging depth with the threshold imaging depth; and automatically configure the ultrasound device to switch between the shallow lung imaging mode and deep lung imaging mode, depending upon a result of the comparison of the user-selected imaging depth with the threshold imaging depth.

Methods and apparatuses for ultrasound imaging of lungs

Aspects of the technology described herein relate to techniques for guiding an operator to use an ultrasound device. Thereby, operators with little or no experience operating ultrasound devices may capture medically relevant ultrasound images and/or interpret the contents of the obtained ultrasound images. For example, some of the techniques disclosed herein may be used to identify a particular anatomical view of a subject to image with an ultrasound device, guide an operator of the ultrasound device to capture an ultrasound image of the subject that contains the particular anatomical view, and/or analyze the captured ultrasound image to identify medical information about the subject.

Augmented reality interface for assisting a user to operate an ultrasound device

A graphical user interface displayed by a processing device in operative communication with an ultrasound device may include a preset filter option that provides an easy way to switch between different presets which belong to a preset family. The user uses the preset filter feature to cycle through the different presets in the family while remaining on the same screen that is showing ultrasound images collected in real time. The imaging depth remains the same while the user is using the preset filter feature to select the preset within a family. Other settings such as time-gain compensation may not remain the same when cycling between presets. The preset filter feature allows a user to continuously view and assess the ultrasound images being collected in real time while cycling through the presets in the family.

System and method for graphical user interface with filter for ultrasound image presets

Some aspects of the technology described herein relate to configuring an ultrasound device to perform a three-dimensional ultrasound imaging sweep, and displaying ultrasound images and segmented portions of the ultrasound images as the ultrasound images are collected during the three-dimensional ultrasound imaging sweep. Certain aspects relate to displaying an ultrasound image collected by an ultrasound device and configuring the ultrasound device to perform a three-dimensional ultrasound imaging sweep based on the ultrasound image collected by the ultrasound device.

Methods and apparatuses for collection and visualization of ultrasound data

Aspects of the technology described herein relate to detecting degrade ultrasound imaging frame rate. Some embodiments include receiving ultrasound data from the ultrasound device, generating ultrasound images from the ultrasound data, taking one or more measurements of ultrasound imaging frame rate based on the ultrasound images, comparing the one or more measurements of ultrasound imaging frame rate to an reference ultrasound imaging frame rate value, and based on a result of comparing the one or more measurements of ultrasound imaging frame rate to the reference ultrasound imaging frame rate value, providing a notification and/or disabling an ultrasound imaging preset and/or an ultrasound imaging mode with which the ultrasound device was configured.

Methods and apparatuses for detecting degraded ultrasound imaging frame rates

Aspects of the technology described herein relate to ultrasound imaging of lungs. An ultrasound device may be configured with a set of parameter values associated with a shallow lung imaging mode. A selection of a change in imaging depth may be received. If the selected imaging depth is greater than or equal to a threshold imaging depth, the ultrasound device may be configured with a set of parameter values associated with a deep lung imaging mode. The set of parameter values associated with the shallow lung imaging mode may be optimized for imaging lung sliding and the set of parameter values associated with the deep lung imaging mode may be optimized for imaging A lines and B lines.

Ultrasound devices and methods are described for collecting ultrasound data. An ultrasound device may include an ultrasound transducer array. The ultrasound device may collect ultrasound data along multiple elevational steering angles with respective apertures of different sizes. The ultrasound data may be used to perform a measurement or generate a visualization.
