Ultrasound uses no ionizing radiation, and it can image directly in any body plane. In practice, an ultrasonographer (either an ultrasound technologist called a sonographer or a physician) places gel on the patient’s skin and moves a transducer across the surface of the patient’s body. The gel forms an acoustic seal between the transducer and the skin for better transmission of sound, which results in better images.
