MRI
Creation of images
Placing patient into a strong magnetic field
- 30 000 x stronger than the earth's magnetic field
Stronger magnets, better images, shorter times
- 1.5 Tesla
- 3 Telsa
The nuclei of elements with odd numbers of protons line up
- i.e. hydrogen atoms
- hydrogen is plentiful in fat and water
A radiofrequency is then applied, exciting the protons
