ULTRASOUND
An ultrasound procedure is a non-invasive (the skin is not pierced) diagnostic procedure used to assess soft tissue structures such as muscles, blood vessels, and organs.
Ultrasound uses a transducer that sends out ultrasonic sound waves at a frequency too high to be heard. When the transducer is placed at certain locations and angles, the ultrasonic sound waves move through the skin and other body tissues to the organs and structures within. The sound waves bounce off the organs like an echo and return to the transducer. The transducer picks up the reflected waves, which are then converted by a computer into an electronic picture of the organs or tissues under study
Technological advancements in the field of ultrasound now include images that can be made in a three-dimensional view (3-D) and/or four dimensional (4-D) view. The added dimension of the 4-D is motion, so that it is a 3-D view with movement.
