Ultrasound scanning is a medical imaging technique that uses high-frequency soundwaves and their echoes to display a two-dimensional figure on a monitor. Ultrasonic soundwaves are generated and received by the transducer probe, which emits soundwaves through the soft tissue of the animal's body. The frequency used is determined by the density of the tissue (fat, muscle or bone). These sound waves 'bounce' off the boundaries between tissues, for example, between fluid and soft tissue or soft tissue and bone, and are reflected back to the probe. The information is then interpreted by the machine's central processing unit, and an image is generated and displayed.
