If the transmitter is placed in the abdomen at a specific location location, the ultrasonic waves penetrate through the skin and other tissues to the organs.

bodies reflect the sound waves on the principle of echo, and wave back into the converter, which receives them, converting to turn to the electronic organ image.

Various human tissues have different speeds transmitting ultrasonic waves.The fastest transmission rate observed during the passage of the waves through the bone, and the slowest speed - when passing through air.Before the diagnosis to the patient's skin in the survey applied a special gel that improves the movement of the transducer, as well as get rid of the air between the skin and the device.
