Medical applications of physics
1 X-rays
1.1 Electromagnetic waves
1.1.1 All waves in the electromagnetic spectrum are transverse waves which can travel through a vacuum
1.1.2 Shorter wavelengths travel the most energy
1.1.3 Gamma rays, x-rays and some ultra-violet rays have enough energy to remove electrons from atoms or molecules and form ions
1.1.3.1 This is called ionisation
1.1.3.1.1 ionising radiation can:
1.1.3.1.1.1 Harm the body
1.1.3.1.1.2 Kill cells
1.1.3.1.1.3 Damage a cells DNA
1.1.3.1.1.3.1 Cause a mutation leading to cancer
1.2 X-ray images
1.2.1 Photographic film exposed to x-rays will turn black
1.2.2 X-rays are transmitted through some materials that are opaque to visible light such as healthy human tissue
1.2.3 Other materials, such as metal and bone, absorb x-rays, and some materials partially absorb them
1.3 CT Scans
1.3.1 Computerised tomography is used to build up a three-dimensional image of the inside of an object
1.3.2 To make one, X-ray images are taken from a number of different positions and angles
1.3.2.1 All the results are processed in a computer to build a three-dimensional X-ray image
1.3.2.1.1 It can then be processed in a number of ways, depending on the nature of the investigation carried out
