"Echography
The visualization of deep structures of the body by recording the
reflections of echoes of pulses of ultrasonic waves directed into the
tissues. Use of ultrasound for imaging or diagnostic purposes employs
frequencies ranging from 1.6 to 10 megahertz."

"Echocardiography

and surrounding tissues. The standard approach is transthoracic."
