Test your basic knowledge |

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Has a filament made of tungsten - due to the high melting point






2. This is inversely proportional to screen speed






3. Rotating anode






4. When.....collide with the anode - 99% of energy is released in the form of heat - and 1% of energy is in the form of x-rays






5. X-ray gloves have to have....of lead equivalent






6. Redness of the skin






7. An abdominal radiograph should be taken at the peak of expiration






8. The x-ray machine we've been using has a rotating anode






9. Has a positive charge






10. Film with: ultra speed - grainier image - less exposure needed






11. Most commonly used film - compromise between graininess and speed (detail)






12. If the x-ray tube is not 36-40 inches from the grid - this is called the






13. Incorrect grid focus is one reason for






14. Distance from the grid to the x-ray tube (36-40 inches)






15. Is the density difference between 2 adjacent areas on a radiograph






16. To double the density






17. We should always try and stay How many feet from our x-ray machine






18. These screens are high speed - they decrease exposure - poorer detail - able to penetrate thicker areas






19. Slowly growing dividing cells are the most sensitive to the effects of ionizing radiaton






20. Pigments tend to decrease the lateral spread of light so there is increased detail






21. This is used to take 'real-time' radiographs - used a lot in horses






22. Between density and kVp






23. Increased crystal size.....






24. AgBr + light =






25. Within the collimator outlines just how much is collimated






26. If the kVp is too high






27. Refers to the 'blackness' of a radiograph






28. What is the term for an unknown cause






29. Film with: high detail - minimal graininess - increased exposure






30. When the AgBr reacts and ionizes with light or x-rays - than at this point - What is on the film is known as the






31. This pertains to the size of the electron cloud and thus directly to the number of x-ray produced






32. Improper centering of grid is one reason for






33. What spinal problem do doberman's get






34. Sheets of luminescent phorphor crystals on a cardboard or plastic base






35. What is the term for when the animal's bowel engulfs a piece of bowel distal to it - causing blockage






36. A lightproof encasement designed to hold x-ray film and intensifying screens in close contact






37. Why do we not give atropine with a contrast radiograph






38. Is the most common artifact in radiography






39. What needs to have high levels of x-ray absorbtion






40. This gives you the desired mAs - and it gives less time for your patient to move






41. Calcium 'bridges' between adjacent vertebrae






42. Negative contrast agents appear what color on a radiograph






43. Increase what value to penetrate thick body parts






44. If you use an mA of 300 - What time fraction must i use to get an mAs of 10?






45. Is the measurement for the maximum energy available at that setting






46. These crystals will turn white/clear when processing film






47. In the dark room - the safe light (red light) needs to be at least how far away from the loading bench






48. Gelatinous center of disk - pinches spinal cord to cause herniated disk






49. Lead equivalent for apron






50. Outer layer of disk ( dries out and cracks and causes disk to herniate)
