Study Notes
General Radiography and X-rays
- General radiography is the most fundamental form of medical imaging, used for routine diagnostics to produce X-ray images of the inside of the body.
What are X-rays?
- X-rays are highly penetrating, ionizing radiation with enough energy to remove tightly bound electrons from an atom's orbit, causing the atom to become charged or ionized.
- X-rays are used to take images of dense tissues such as bones and teeth because they absorb radiation more than soft tissues.
How X-rays Work
- X-rays radiated from a source pass through the body and onto a photographic cassette.
- Areas where radiation is absorbed show up as lighter shades of grey, used to diagnose broken or fractured bones.
Components of an X-ray Diagnostic System
- X-ray tube, X-ray generator, tube stand, examination table, bucky, and control unit.
- Cassettes, intensifying screens, and film.
- Darkroom equipment and other supplies for processing the exposed film.
- Radiation protection devices.
Note
- Ionizing radiation is radiation with enough energy to remove tightly bound electrons from an atom's orbit, causing the atom to become charged or ionized.
