Ultrasound Imaging

Key Stage 4

This picture shows an ultrasound image of a foetus inside a uterus.

Ultrasound imaging is a technique that uses ultrasound to form an image of the internal structure of an object.

Ultrasound can be reflected, refracted or absorbed at the interface between different media. This can be used, along with a computer, to create images of the internal structure of an object. This is particularly useful for opaque object.

Ultrasound is generally used to detect cracks in large metal structures using echolocation.

Ultrasound is used in hospitals to create images of organs and of the foetus of pregnant females.
