Ultrasound uses sound, or more accurately, sound waves or vibrations, to travel through a medium of some sort to image what is within that medium. Not unlike radar, some of the sound waves bounce off of things within that medium allowing them to be seen. In example, the dividing line between muscle and bone can be thought of as an interface, something the sound waves can bounce off of. The change in density from muscle to bone, allows the bone to be image.
Most ultrasound systems are designed to work best in water environments. This is because most of the solid parts of a body, including organs, bones, and other things, reside in, or are made up of mostly water. Water can carry sound waves better than air. Therefore, water-favoring ultrasound system can’t image well in air. For a water-based ultrasound system, air can act like a barrier to the sound waves. And, much like a brick wall stops you from seeing what is on the other side of the wall, air can prevent ultrasound from seeing what is there. By drinking water, one reduces the amount of air in the stomach and, therefore, improves the image quality of the ultrasound in that region of your body.
However, there are other systems that use sound to image such things as geologic features underground, or things within the air (like the natural imaging bats do using sound). So, what you want to see or image, determines the type of sound-imaging system used.
