A two-dimensional array transducer probe is used to image regions of the body that are acoustically obstructed from conventional view by objects such as the lungs or ribs. The probe is located against the body at an acoustic window which provides acceptable ultrasonic transmissivity between the transducer array and the body. While maintaining the probe at its acoustic window, an image plane location is manipulated by adjusting the beam steering directions. The image plane can be tilted in the elevation direction, moved laterally, and/or rotated about a center axis to position the image plane so that the obstructed anatomy is effectively imaged for diagnosis.
