Across
- 4. how sharply dark and light areas are differentiated or separated on an image; the difference in density
- 8. distance from source of radiation to the client’s skin
- 11. if mA is greater than _____, excessive heat production in the x-ray tube head
- 13. kVp is considered q______
- 14. Quality of wavelength and energy of the central ray is controlled by ________. Controls the speed of electrons from the cathode to the anode. Regulates the speed and energy of electrons
- 15. Filters remove low-energy, less penetrating, longer wavelengths
- 16. the current in the x-ray tube
- 17. distance from source of radiation to the tooth
- 18. distance from source of radiation to the film (receptor)
Down
- 1. Describes the energy and penetrating ability of the x-ray beam
- 2. Measurement of electrical force that causes electrons to move from the negative cathode to positive anode – this is all happening inside the x-ray tube head
- 3. distance from the object to the film
- 5. unit of measurement used to describe the number of electrons, or current flowing through the cathode filament. "weight" of electrons
- 6. To reduce the intensity of the x-ray beam by 1/2 or 50%, aluminum filters are placed in the path of the beam inside the dental x-ray tube head
- 7. mA is considered q______
- 9. mA and exposure time are _______ related
- 10. the relationship between distance and intensity of radiation. The farther the x-ray beam travels from its source, the less intense the beam becomes.
- 12. overall darkness or blackness of an image
