In the medical profession, a couple of medical devices are often used as compared to others. Some are extremely specialized, and others have multiple uses. One device that is widely used in many different areas of medicine is ultrasound. It is valuable in helping doctors locate and treat illnesses and just in monitoring what is going on in the body.

Ultrasound imaging works by sending high frequency sound waves into a body. These waves bounce off of whatever is inside, and those reflections are transferred into an image on the monitor. This is a very safe method of internal viewing, when compared with other methods such as x-ray. It is safe enough to be used on fetuses in the womb, and this is one of the very important uses of ultrasounds.

The sound waves are transmitted directly, and a 2 dimensional picture of image will be captured. 3D ultrasounds can also be done, but in these, the waves are sent down at different angles and the images are combined to create the 3D effect. 4D ultrasound is when these images are recorded in rapid succession and play together to show movement of the fetus.
