Tissue Density | Anatomic structures such as bone or fat that will absorb more or less radiation. |
X-ray beam | Cone shaped concentration of x-rays in the radiation field. |
X-ray field | The cross section of the x-ray beam at the point where it is utilized. |
Central ray | An imaginary line in the center of the x-ray beam, perpendicular to the long axis of the x-ray tube. |
X-ray port | An opening through which x-rays traveling in a useful direction exit the tube housing. |
X-ray tube | The most important part of the x-ray machine. |
Remnant radiation | Exit radiation. Radiation that exits throught the opposite side of the patient after the exposure is made. |
Latent image | An invisible pattern of exposure caused by radiation passing through a film holder and an x-ray film. |
Scatter radiation | Travels out from the absorbing material in all directions, causing unwanted exposure to the film and to anyone who is in the room. |
Attenuation | Absorption of the x-ray beam. |
Radiation fog | Unwanted film exposure caused by scatter radiation. |
Image receptor system | Consists of the x-rays film and the film holder. |
Cassette | Protects the film from damage and exposure to light during radiography. |
Computed radiography (CR) | These imaging systems use special image receptors instead of film. |
Collimator | A box-like devise attached under the tube housing. It allows the radiographer to vary the size of the radiation field. |
Control booth | Contains the control console. Usually has a lead glass window so that the radiographer can observe the patient during the exposure. |
Trendelenburg position | The head lowered at least 15 degrees |
Detent | A special mechanism that tends to stop a moving part in a specific location. |
