Across
- 2. exposure reduced by the square of the distance from the patient
- 3. an increase of image size of the object compared with its actual size
- 4. consist of mostly empty space
- 6. white "crescent" marks
- 8. radiation is measured with this
- 9. as low as reasonably achievable
- 11. radiographic misrepresentation of either the size or shape of the anatomic part
- 12. a radiographic chart that identifies reliable exposure for a known thickness
- 15. the portion of the x-ray image that is sharp and clearly collimated
- 17. the outside edge or shadow where the film has been imperfectly collimated
- 18. partner to the cathode in the x-ray tube'
- 19. occur by chance and may occur without a threshold level of dose
- 20. cells dividing and subdividing
Down
- 1. German scientist that discovered a glowing platinocyanide plate
- 5. the anode consist of this material
- 7. Controls the size of the X-ray beam and prevents it from spreading wider than necessary
- 10. intensity of the radiation is greater on the cathode side than on the anode side.
- 13. an alternative method of developing a variable kV technique chart
- 14. developed to absorb scattered and secondary radiation
- 16. process by which genetic cells divide and subdivide
