Principles of x-rays
Radiology POS 801
Question | Answer |
---|---|
amperage | The number of electrons that pass through a conductor; the strength of an electrical current |
contrast | the difference in degrees of blackness between adjacent areas on a radiograph |
density | the overall darkness or blackness of a radiograph |
kilovoltage | In radiography the x-ray tube peak voltage used during an exposure; measured in kilovolts |
milliamperage | the intensity of the x-ray tube current used during exposure; measured in milliamperes |
genetic effects | effects of radiation that are passed on to future generations through genetic cells |
somatic effects | radiation effects that are responsible for poor health |
cumulative effects | The additive effects of repeated radiation exposure |
sievert | unit of measurement for dose equivalent |
latent period | The invisible image produced when the film is exposed to x-rays, remains invisible until the film is processed. |
collimation | restriction of the size and shape of the x-ray beam |
dental radiograph | a photographic image produced on film by the passage of x-rays through teeth and supporting structures |
dental radiographer | any person who positions,exposes, and processes dental x-ray film |
focal spot | the size of the tungsten target of the anode |
inherent filtration | filtration placed in the x-ray tube by the manufacturer. |
