MODEL RELEASED. Ultrasound scan. Doctor carrying out an abdominal ultrasound examination on a male patient. Ultrasound scanning uses high frequency sound waves to form an image of internal body structures and to search for such things as tumours and abscesses. A transducer held against the man's abdomen emits the sound waves in short pulses and acts as a receiver for returning echoes. Echoes are created as each ultrasound pulse meets the boundary between two tissues of different densities. The monitor at upper centre displays the resulting image | |
