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： An illustrative controller includes: a transmitter to drive an acoustic transducer to generate a first acoustic burst and a second acoustic burst; a receiver coupled to the acoustic transducer to sense a first response to the first acoustic burst and a second response to the second acoustic burst; and a processing circuit to derive output data from the first and second responses in part by determining an offset frequency difference between the first and second responses, wherein the first acoustic burst has a first characteristic frequency and the second acoustic burst has a second characteristic frequency different from the first characteristic frequency.

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： According to one embodiment, an ultrasonic diagnostic apparatus includes processing circuitry. The processing circuitry computes depths of field of each of scan lines based on an ultrasonic image. The processing circuitry computes a corrected transmission voltage that makes the depths of field of the scan lines substantially uniform. The processing circuitry executes control to transmit an ultrasonic beam based on the corrected transmission voltage.

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.

摘要： A method for calculating a diagnostic parameter for pneumonia, comprising the steps of: (100) acquiring a plurality of ultrasound images of the lung in a first acquisition position, (200) individuating inside each image the area under the pleural line; (300) individuating a plurality of ultrasound makers (C1, . . . , Cn) therein; (400) calculating for each marker (C1, . . . , Cn) a plurality of features (C11, . . . , C1m, . . . , Cn1, . . . , Cnm) (450) calculating at least another parameter relating to all the images acquired at point (100) as a whole, comprising the percentage of pleural line interested by “White lung”; (500) calculating a diagnostic parameter with a two steps procedure: a first step, in which to each image a first value of Pneumonia Score is assigned and a second step in which the average of the first values calculated for each image acquired at point (100) is corrected as a function of said further parameter calculated at point (450).
