Abstract
An ultrasound system includes a transducer array having three or more rows of transducer elements extending in the azimuth dimension and located adjacent to each other in the elevation dimension. The rows have different mechanical foci in the elevation dimension, with an inner row elevationally focused in the near field and outer rows elevationally focused in the far field. When the user is imaging a subject in the near field, the system beamformer transmits with the inner row with a near field elevation focus. When imaging in the far field a plurality of rows elevationally focused in the far field are used for transmission. When the user is imaging in the mid-range, the beamformer uses both the inner row and the plurality of outer rows to provide an extended mid-range elevation focus.
