- Ultrasound Scanning
- uses a transducer to produce high frequency sound waves
- a lubricating gel is put onto skin to ensure good contact between transducer and skin
- sound waves can be reflected off surfaces inside the body
- reflections are picked up by a receiver and converted into images
- low risk of harm to foetus
- provides real time moving image
- used in pregnancy
- cannot penetrate bone so no good for brain scans
