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. Is located in a focusing cup made of molybdenum which has a high melting point and helps to direct the electrons produced toward the cathode






2. Calcium 'bridges' between adjacent vertebrae






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






4. The efficiency of this reflects light made by phosphors back towards the film






5. Affects both density and contrast

12. Improper centering of grid is one reason for






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






14. As this increases - the intensity of the x-ray beam decreases - so the beam intensity increases - and the mAs must decrease to compensate






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






16. Is only 1/3 the size of the actual focal spot






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

19. If barium leaks into the abdomen or lungs - it can cause what






20. A grid must be used on the chest if it's 11cm thick






21. AgBr + x-rays =






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






23. What is the term for the spotty appearance on the film due to the large crystals in the screens






24. If there's no object in the way of an x-ray - the picture would be






25. Weakness






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






27. Is the source of electrons






28. A layer of intensifying screen that reflects the light from the phosphor layer toward the film






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






30. Between density and mAs






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






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






33. Safe Operating Procedures






34. Must increase.....to compensate for x-ray absorption by the grid. (we triple our mAs)






35. What is the term for an unknown cause






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






37. A device that moves the grid back and forth under the table. it helps to prevent grid lines from showing

44. Increase what value to penetrate thick body parts






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






46. This is inversely proportional to screen speed






47. Rotating anode






48. Extra vertebrae - scoliosis - fused vertebrae are all examples of






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






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