- Using X-Rays
- Inverse square law
- The strength of radiation decreases the further it gets away from the source.
- Absorption of X-Rays
- Different materials absorb different amounts of X-rays
- The thicker the material, the more X-rays it absorbs.
- CAT Scans & Fluoroscopes
- In a CAT Scan, an X-ray source is moved around the patient in a circle.
- X-ray detectors build up many cross-sectional views of the body.
- Fluoroscopes are used to show a patients organs are working.
- In a CAT Scan, an X-ray source is moved around the patient in a circle.
