How does ultrasonography work? Ultrasonography uses ultrasound to produce images or photographs of organs and tissues. Ultrasonic echoes are recorded as they strike tissues of different densities. Ultrasound itself is made of inaudible sound waves in the frequency range of about 20,000 to 10,000,000,000 cycles per second. Ultrasound has different velocities in tissues which differ in density and elasticity from others. This allows the use of ultrasound in outlining the shape of various tissues and organs in the body. Use of ultrasound for diagnostic and therapeutic purposes requires special equipment.
