An ultrasound imaging system includes a transducer array () with a plurality of transducer elements () configured to transmit an ultrasound signal, receive echo signals produced in response to the ultrasound signal interacting with stationary structure and flowing structure, and generate electrical signals indicative of the echo signals. The system further includes a beamformer () configured to process the electrical signals and generate sequences, in time, of beamformed data. The system further includes a filter () configured to process the beamformed data, and remove or replace a set of frequency components based on a threshold, producing corrected beamformed data. The system further includes a flow processor () configured to estimate a velocity of flowing structure from the corrected beamformed data. The system further includes a rendering engine () configured to display the flow velocity estimate on a display ().

Ultrasound flow imaging

An ultrasound imaging system () includes a 2-D transducer array () with a first 1-D array () of one or more rows of transducing elements () configured to produce first ultrasound data and a second 1-D array () of one or more columns of transducing elements () configured to produce second ultrasound data. The first and second 1-D arrays are configured for row-column addressing. The ultrasound imaging system further includes a controller () configured to control transmission and reception of the first and second 1-D arrays, and a beamformer () configured to beamform the received first and second echoes to produce ultrasound data, and an image processor () configured to process the ultrasound data to generate an image, which is displayed via a display ().

3-D imaging and/or flow estimation with a row-column addressed 2-D transducer array

A transducer array () for an ultrasound imaging system () includes a row-column addressed 2-D array of transducer elements (). The row-column addressed 2-D includes a first array of 1-D arrays of elements, a second array of 1-D arrays of elements, which is orthogonal to the first array, and a double-curved surface (). In another aspect, an apparatus includes a transducer array with an array-wise addressable 2-D array with a curved surface. The 2-D array includes a set of 1-D column array elements and a set of 1-D row array elements. The apparatus further includes transmit circuitry () that conveys an excitation pulse to the transducer array, receive circuitry () that receives a signal indicative of an ultrasound echo from the transducer array, and a beamformer () that processes the received signal, generating ultrasound image data.

Row-column addressed 2-D array with a double curved surface

An ultrasound imaging system includes a transducer array. The array is configured for row-column addressing. The array of transducer elements includes a plurality of first 1-D arrays and a plurality of second 1-D arrays, which is orthogonal to the plurality of first 1-D arrays. The array of transducer elements further includes a plurality of front-end circuits. A single front-end circuit of the front-end circuits is in electrical communication with a single pair of 1-D arrays, which consists of a first 1-D array of the plurality of first 1-D arrays and a second 1-D array of the plurality of second 1-D arrays. The first and second 1-D arrays are either separate sets of 1-D arrays or part of a same 2-D array. In one instance, for N rows and N columns, a number of electrical connections between the elements and front-end electronics are less than 2N.

Row-column addressed array with N rows and N columns and with less than 2N electrical connections

An ultrasound imaging system includes a probe and a console. The probe includes a row-column addressed transducer array, first beamformer configured to beamform echo signals received by the row-column addressed transducer array and produce a set of image planes for each emission with a single focus in both transmit and receive, and a first communication interface. The console includes a second complementary communication interface and a second beamformer configured to beamform the focused set of image planes and produce a three-dimensional volume of ultrasound data.

Three-dimensional (3-D) imaging with a row-column addressed (RCA) transducer array using synthetic aperture sequential beamforming (SASB)

An ultrasound transducer probe () includes a transducer array () of elements () that emit an ultrasound signal and receive analog echo signals produced in response thereto and a beamformer (), housed by the probe, that converts the analog echo signals to digital signals, applies delays to the digital signals, and sums the delayed digital signals, produces a value of a bit stream, wherein the beamformer apodizes the signals.
