What are X-rays?
• Frequency, wavelength?

How does X-ray imaging work?• Transmitted by? Absorbed by?
• Photographic film? Or CCD’s?

X-ray therapy
![Page 9: X-Rays Lo: To know how x-rays are used in medical physics.](https://reader035.fdocuments.in/reader035/viewer/2022062317/5a4d1b277f8b9ab059997c04/html5/thumbnails/9.jpg)
X-ray therapy• Ionising rays.
• Danger to all cells.
• Focus ray and rotate around tumour to minimise damage to body cells.

CT scans (computer tomography scanner)

CT Scanner• This builds up a 3D image of an organ as X-rays are taken
from all angles in a cross section and put together
How would the dosage compare to a normal X-ray?
