The Principles of Medical Ultrasound Whenever a sound wave moving in air hits a solid surface, it reflects off it. This reflected sound is called an echo. The same applies to a sound wave moving through water and hitting an obstacle. If we know the speed of sound in the air or water, we can calculate the distance to the obstacle.
3D ultrasound - we can use it to image objects concealed from the eye. It has been used since the beginning of this century in medical, geological and oceanographical applications. Related Links:
