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. Collimator






2. To double the density






3. The exact area of the anode that the electrons hit






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






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






6. What type of film gives more detailed radiographs but more exposure to everyone involved? (commonly used as dental film - or for extremities)






7. Safe Operating Procedures






8. Infection of a disk - or bone near it






9. Increased thickness of this leads to increased x-ray absorption and increased visible light emission from the crystals






10. Another result of the 20 degree angling






11. AgBr + light =






12. The shorter the wavelength of the x-ray - the more powerful the x-ray is






13. The distance from the x-ray tube to the x-ray machine is the SID (source image distance) - or the FFD (also known as....)






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






15. What type of film has the x-rays directly cause the latent image to be formed






16. White against black - like the x-ray of a plain skeleton






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






18. If the kVp is too low






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






20. Within the collimator outlines just how much is collimated






21. Is determined by the ratio of the height of the lead strips to the distance between them






22. Is on the anode and is angled at approximately 20 degrees from vertical






23. 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






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






25. Positive contrast agents appear what color on a radiograph






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






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






28. 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






29. Bone infection - also known as spondylitis






30. Bone - lymphatic cells - epitheilial - and hemopoietic cells are also what kind of cell?






31. Loss of movement in legs (front and/or back)






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






33. Is to the left - electrons bounce off it at a 20 degree angle






34. Between density and mAs






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






36. If perforation is suspected - what compound do we use when radiographing






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






38. The tendency of a luminescent compound to continue to give off light after x-radiation has stopped






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






40. When processing film - the black areas are made of






41. When doing a lateral radiograph of the thorax/chest - the x-ray beam should be centered over what specific anatomical landmark






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






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






44. Ideally is very small






45. A clear protective layer on radiographic film






46. What specific part of the eye is cloudy with a cataract






47. On a lateral view of the chest the aorta is dorsal to the caudal vena cava






48. Film with silver crystals that is more sensitive to fluorescent light emitted from intensifying screens than to ionizing radiation






49. Film that is more sensitive to ionizing radiation than to fluorescent light






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