摘要： A device and method for imaging, measuring and identifying multiphase fluid flow in wellbores using phased array Doppler ultrasound. The device includes a radially-configured or ring-shaped ultrasound transducer that when deployed in a well in Doppler mode can measure the velocity of radially flowing fluids in the wellbore and generate a 3D image of radial flow in the wellbore, including flowback into the wellbore after fracturing operations, or flow leaving the wellbore during water injection operations. The ring-shaped ultrasound transducer can also simultaneously operate in a B-mode to generate a B-mode image of the wellbore liner upon which the Doppler image can be overlaid. The device may also include a forward facing ultrasound transducer either instead of or in place of the ring-shaped transducer for obtaining information and images on axial flow in the wellbore in Doppler mode, and the location of phase boundaries and phase locations in B-mode.

摘要： A plurality of images can be acquired from a plurality of sensors and a plurality of flattened patches can be extracted from the plurality of images. An image location in the plurality of images and a sensor type token identifying a type of sensor used to acquire an image in the plurality of images from which the respective flattened patch was acquired can be added to each of the plurality of flattened patches. The flattened patches can be concatenated into a flat tensor and add a task token indicating a processing task to the flat tensor, wherein the flat tensor is a one-dimensional array that includes two or more types of data. The flat tensor can be input to a first deep neural network that includes a plurality of encoder layers and a plurality of decoder layers and outputs transformer output. The transformer output can be input to a second deep neural network that determines an object prediction indicated by the token and the object predictions can be output.

摘要： Range finding methods and apparatus that may be implemented by VR/MR systems that include a head-mounted display (HMD) and an accessory that the user holds or wears. Range finding sensors (e.g., ultrasonic transducers) may be included on the HMD and on the accessory and used to track distances to and relative position of walls, objects, and other obstacles within constrained physical environments such as rooms, gyms, yards, or fields, or in unconstrained physical environments. Range finding information from the sensors on the HMD and accessory can be used to generate a 3D map of the user's environment that can be used for various purposes in the VR/MR system. In addition to mapping the user's environment, the range finding methods and apparatus may also be used to track the relative position of the accessory with respect to the HMD.

摘要： Techniques, systems, and devices are disclosed for synthetic aperture ultrasound imaging using spread-spectrum, wide instantaneous band, coherent, coded waveforms. In one aspect, a method includes synthesizing a composite waveform formed of a plurality of individual orthogonal coded waveforms that are mutually orthogonal to each other, correspond to different frequency bands and including a unique frequency with a corresponding phase; transmitting an acoustic wave based on the composite waveform toward a target from one or more transmitting positions; and receiving at one or more receiving positions acoustic energy returned from at least part of the target corresponding to the transmitted acoustic waveforms, in which the transmitting and receiving positions each include one or both of spatial positions of an array of transducer elements relative to the target and beam phase center positions of the array, and the transmitted acoustic waveforms and the returned acoustic waveforms produce an enlarged effective aperture.

摘要： An ultrasound imaging system integrated on a chip for autonomous scanning includes an on-chip input memory configured to store scan sequence instructions and parameters, an on-chip processor configured to read the scan sequence instructions and parameters in the input memory, and an on-chip beamformer configured to be programmed and timed by the processor according to the scan sequence instructions and parameters. In some examples, the scan sequence instructions and parameters are stored in a nonvolatile input memory programmed at the factory. In other examples, they are received from an external user device. The scan parameters are optimized or minimized to accommodate the limited input memory capacity. In some examples, the scan sequence instructions and parameters include programmable nested loops, and each of the programmable nested loops corresponds to a transmit and/or receive event in a scan sequence.

摘要： A computer-implemented method for training and using a neural network to predict a coherence function includes: training a neural network by mapping a plurality of different sets of training input samples to respective coherence function truths to generate a trained neural network; receiving an operational input sample; inputting the operational input sample into the trained neural network; obtaining, from the trained neural network, a coherence function mapped to the operational input sample in response to the inputting the operational input sample into the trained neural network; and executing a computer-based instruction based on obtaining the coherence function. The coherence function may be used to differentiate solid masses from fluid-filled masses.

摘要： The present invention related to an ultrasound imaging system win which the scan head includes a beamformer circuit that performs far field subarray beamforming or includes a sparse array selecting circuit that actuates selected elements. When using a hierarchical two-stage or three-stage beamforming system, three dimensional ultrasound images can be generated in real-time. The invention further relates to flexible printed circuit boards in the probe head. The invention furthermore related to the use of coded or spread spectrum signaling in ultrasound imagining systems. Matched filters based on pulse compression using Golay code pairs improve the signal-to-noise ratio thus enabling third harmonic imaging with suppressed sidelobes. The system is suitable for 3D full volume cardiac imaging.

摘要： Systems and methods for presenting marine data are provided herein. The system comprises at least one sonar transducer associated with a watercraft, a display, one or more processors and a memory. The memory including computer program code configured to cause presentation of a chart on the display including at least a portion of the body of water, at a first zoom level. The system further causes emission of one or more sonar beams by the at least one sonar transducer and receives sonar data corresponding to the sonar returns received by the at least one sonar transducer. The system generates and presents a sonar image based on a sonar image scale. The system automatically adjusts the presentation of the chart to a second zoom level that corresponds to the sonar image scale. The second zoom level being different than the first zoom level.

摘要： For ultrasound imaging with an ultrasound scanner, fat fraction of the tissue is measured. The fat fraction may be measured without access to channel data, such as from beamformed data. The speed of sound varies with the fat fraction of tissue, so the fat fraction is used to set the speed of sound in beamforming. Imaging the tissue using the fat fraction-based optimization for speed of sound may provide better images than imaging with an assumed speed.
