Abstract
An ultrasound transducer system is provided which produces a wide area scan of a body being imaged. The ultrasound transducer includes an array of N×M transducer elements, with the transducer elements preferably arranged in columns and rows. The transducer array comprises M columns of N elements each, with M and N being integers. The ultrasound transducer system further includes a transmitter for generating transmission signals and a receiver for receiving and processing ultrasound backscatter signals. A first switching arrangement sequentially connects the transmitter to subarrays of N×X transducers each so as to sequentially energize the subarrays to generate ultrasound interrogating beams across the face of the array. A second switching arrangement is provided which sequentially couples the receiver to each energized subarray to enable the reception and processing of acoustic signals from each subarray, in sequence. Because each individual subarray is steered only in the elevational direction, only the N transducers need to be spaced ≦0.5&lgr;. Transducers spaced along the long axis of the array may be spaced up to 2&lgr; apart.
