ALARA Concept |
Concept of radiation protection that states that all exposure should be kept "as low as reasonably achievable."
|
|
|
Central Ray |
X-rays at the center of the beam |
|
|
Radiolucent |
Body structures that radiation can easily pass through that appear dark on an image (ex. air spaces, soft tissues, abscesses, tooth decay, and dental pulp.) |
|
|
Radiopaque |
Body structures that radiation does not easily pass through appear white or light gray on an image (ex. tooth enamel, dense areas of bone and metal restorations.) |
|

|
Extraoral Film |
Film designed for use in cassettes |

Teeth appear too short from excessive vertical angulation |
|
|
Elongation |
