terminology
| Question | Answer |
|---|---|
| concept of radiation protection that states all exposures should be kept “as low as reasonably achievable” | ALARA |
| negative electrode in the x-ray tube | cathode |
| overall darkness or blackness of an image | density |
| keeps electrons suspended in an electron cloud at the cathode and directs them toward the target | focusing cup |
| chemical compounds that are sensitive to radiation or light | silver halide crystals |
| highest voltage of x-ray tube used during an exposure | kilovoltage kVp |
| time between exposure to ionizing radiation and appearance of image | latent period//image |
| one one-thousandth (1/1000) of an ampere; a unit of measurement used to describe the intensity of an electrical current | milliamperage |
| same as primary beam | primary radiation |
| body structures that radiation can easily pass through appear radiolucent dark or black image. Ex. (air spaces, soft, abscesses, tooth decay and dental pulp appear as radiolucent images. | radiolucent |
| a form of secondary radiation that occurs when an x-ray beam has been deflected from its path by interaction with matter | scatter radiation |
| x-radiation that is created when the primary beam interacts with matter | secondary radiation |
| a form of energy that travels in waves | X-ray |
| intraoral technique of exposing dental images where the x-ray beam is directed, perpendicular to an imaginary line which bisects the angle. | bisecting technique |
| appears as clear, unexposed area on a dental radiograph and may occur with a rectangular or round PID | cone-cutting |
| teeth appear to short caused by insufficient vertical angulation or vertical angulation that is too flat | elongation |
| the teeth appear to long, results from excessive vertical angulation | foreshortening |
| process by which electrons are removed from atoms, causing the harmful effects of radiation in humans. | Ionization |
| body structures that radiation does not easily pass through appear radiopaque white or light gray on an image | radiopaque |
| shows the bony and soft tissue areas of the facial profile | cephalometric radiograph |
| electronic signals captured by sensors and displayed on computer monitors | digital image |
