Abstract
An ultrasonic imaging system includes an ultrasonic transducer array having a thinner portion, an intermediate portion, and a thicker portion that extend along an azimuthal direction. This transducer array is used to acquire first and second images of an imaged region. The first and second images differ in ultrasonic imaging bandwidth and/or ultrasonic center frequency such that the intermediate transducer portion is active in both the images while at least one of the thinner and the thicker transducer portions is active in only one of the images. The first and second images are then combined to form a composite display image.
