Abstract: 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).

Abstract: 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.

Abstract: An ultrasound system includes a 2-D transducer array and a velocity processor. The 2-D transducer array includes a first 1-D array of one or more rows of transducing elements configured to produce first ultrasound data. The 2-D transducer array further includes 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 velocity processor processes the first and the second ultrasound data, producing 3-D vector flow data. The 3-D vector flow data includes an axial component, a first lateral component transverse to the axial component, and a second lateral component transverse to the axial component and the first lateral component.
