Ultrasound: Background
Background
- Ultrasound scanning uses extremely high frequency sound waves emitted by a transducer device.
- A transducer is a device which transmits and receives the ultrasound waves. These waves travel through
the patient's body, and are reflected back to a variable extent depending on what type of tissue is encountered.
- The acquired signals are then converted into a real time greyscale video which the operator can interpret. Images
can be obtained in any plane and are viewable on the screen by the operator and patient if desired.
