    摘要： An ultrasound imaging system (100) includes a 2-D transducer array (102) with a first 1-D array (104, 204) of one or more rows of transducing elements (106, 2041, . . . 2046) configured to produce first ultrasound data and a second 1-D array (104, 206) of one or more columns of transducing elements (106, 2061, . . . 2066) 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 (112) configured to control transmission and reception of the first and second 1-D arrays, and a beamformer (114) configured to beamform the received first and second echoes to produce ultrasound data, and an image processor (116) configured to process the ultrasound data to generate an image, which is displayed via a display (224).

    摘要： A transducer array (302) for an ultrasound imaging system (300) includes a row-column addressed 2-D array of transducer elements (304). 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 (306). 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 (308) that conveys an excitation pulse to the transducer array, receive circuitry (308) that receives a signal indicative of an ultrasound echo from the transducer array, and a beamformer (314) that processes the received signal, generating ultrasound image data.

    摘要： 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.
