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. To double the density






2. A...is a series of lead strips on edge which only allow the primary x-rays - which are traveling in straight lines - reach the film






3. Positive contrast agents appear what color on a radiograph






4. A clear protective layer on radiographic film






5. With this procedure - no x-ray film is involved at all






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






7. Redness of the skin






8. Is the source of electrons






9. Aluminum filter






10. In which processing solution do unionized (green) AgBr crystals get removed from the film






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






12. What must have little or no 'afterglow'






13. Crystals + x-rays = ?






14. Has a negative charge






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






16. Extra pain is also called






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






18. If there's metal in the way of an x-ray - than no x-rays will get through and that part would be






19. The effective focal spot is only 1/3 the size of the actual focal spot. this is called the






20. Amount of radiation a person can recieve in a calendar year






21. We ideally take a radiograph of the abdomen at the peak of inspiration






22. What are the 2 types of anodes






23. X-ray machines come with a set one - we cannot adjust it






24. Must be radiolucent






25. Lead equivalent for apron






26. MAs for bone views (pelvis - skull - spine) 2x =?






27. Animal has broken femur - it's ideal to have How many radiographs for diagnostic purposes






28. AgBr + light =






29. What type of film has no screens or film cassettes






30. If there's far or muscle in the way of an x-ray - those parts would be






31. If the kVp is too high






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






33. These screens have increased definition/detail - need to have increased radiation exposure






34. The greater the number of electrons released






35. Improper centering of grid is one reason for






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






37. This stage of pregnancy is the most dangerous for the fetus






38. Less forgiving - high contrast - cannot tolerate changes in exposure or processing






39. 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






40. If the grid is stationary - more lines that are finer are less apt to show up on a radiograph - this is called....






41. Is the electrical current that heats the filament






42. Give a 25% barium solution for upper GI series - and give At what dose?






43. Does move - has disks that rotate at high speeds - this helps spread out the heat that's produced as the electrons hit the focal spot






44. Means more electrons will be released from the filament and directed at the anode






45. AgBr + x-rays =
