Ultrasound vs X-ray Photography and CT Scans - Advantages and Disadvantages - GCSE Physics

This tutorial compares the advantages and disadvantages of using ultrasound, x-ray photography and CT (computer tomography) scans to form images for medical diagnosis.
Ultrasound is useful for producing images of soft tissues and is non-ionising and so is much safer than x-rays or CT-scans.
However, ultrasound lacks fine detail (low resolution)
X-ray photography offers good image resolution (2D) of bone structure. However, it is ionising radiation and can damage living tissue. It is also not very good at imaging soft tissue. For these reasons, x-rays are not used for prenatal scanning.
CT-Scans gives high detail of the body in 3D for both bone, soft tissue and blood vessels. However, it works using x-rays and so is ionising radiation which can damage living tissue.
