Respiratory L6.1 Flashcards
1) How does X-Ray Imaging work? (basic concept)
2) X-Ray process:
3) Image Orientation
1) Photography (kind of): X-ray imaging works similarly to photography, but instead of light, it uses X-rays to capture images of the body’s internal structures.
Ionising Radiation (IMER): X-rays use ionizing radiation, which has enough energy to create ions by knocking electrons out of atoms.
2) Beam of Radiation: X-rays are emitted from a transmitter and pass through the body to a receiver (detector or film) on the opposite side.
Image Formation:
No Obstruction (e.g., air): X-rays pass through easily, resulting in a black area on the image (e.g., lungs). Obstruction (e.g., bones, dense tissues): Dense objects block X-rays, appearing as lighter areas (white or gray) depending on their density.
3) A Film (Posterior to Anterior): X-ray beam travels from the patient’s back (posterior) to the front (anterior).
AP Film (Anterior to Posterior): X-ray beam travels from the front (anterior) to the back (posterior).
Lateral View: The X-ray beam travels from one side of the body to the other for a side-on view.
How do we interpret chest X-Rays?
