  • Description: Shortly after World War II, the Japanese started to investigate the use of sound waves to detect and image objects in and out of the water. In an x-ray, as the beam passes through the body, denser items--such as bones--absorb more of the beam, making the image on film or receptor light, while soft tissue absorbs less, making the image darker and less well-defined.
