Abstract
A transducer for use in an ultrasonic imaging system. The transducer includes a plurality of acoustically and electrically independent sub-arrays, wherein each sub-array includes a plurality of transmitting and receiving elements and a backing assembly. Each sub-array is capable of transmitting lines of ultrasonic energy and receiving echo lines containing information for generating an image concurrent with the operation of the other sub-arrays. The sub-arrays are mounted onto the backing assembly to form a single mechanical unit with the backing assembly providing electrical and acoustic isolation between the cub-arrays. An acoustic insulator is placed between each pair of adjacent sub-arrays to isolate each sub-array from adjacent sub-arrays.
