Abstract: 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.

Abstract: 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.

Abstract: Aspects of the technology described herein include ultrasound data collection using different image formats. Some embodiments include causing, within a single imaging preset, an ultrasound device having a single transducer array to switch from a configuration to collect ultrasound data for producing ultrasound images having a first format to a configuration to collect ultrasound data for producing ultrasound images having a second format. Some embodiments include modulating, within a single imaging preset and as a function of imaging depth, a virtual apex location and/or an instantaneous transmit aperture size used for ultrasound data collection by an ultrasound device having a single transducer array.

Abstract: 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.

Abstract: Aspects of the technology described herein related to modifying the location of an ultrasound imaging plane. Some embodiments include modifying the location of the ultrasound imaging plane based on a user selection. For example, some embodiments include receiving the user selection through a graphical user interface (GUI) that includes an ultrasound imaging plane indicator, where the ultrasound imaging plane indicator indicates the location of the ultrasound imaging plane. As another example, some embodiments include receiving the user selection by detecting tilts, taps, or voice commands. Some embodiments include automatically modifying the location of the ultrasound imaging plane. Some embodiments include modifying the location of the ultrasound imaging plane during biplane imaging.
