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 negative charge






2. A type of electromagnetic radiation which have a shorter wavelength than visible light






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






4. Has a filament made of tungsten - due to the high melting point






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






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






7. When this is exposed to x-rays - it will absorb photons (quanta) and give off photons of visible light which the film is sensitive to (give off blue light)






8. Calcium 'bridges' between adjacent vertebrae

10. A clear protective layer on radiographic film






11. What needs to have high levels of x-ray to light conversion with the correct energy and color for the type of film used






12. Dislocations or separations






13. The greater the number of electrons released






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






15. What is one of the most common areas of occurance for spinal problems ( 85% dachshunds)






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






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






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






19. The smaller the focal spot






20. Bone infection - also known as spondylitis






21. Is the source of electrons






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






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






24. NYSVMS Facility Accreditation Standards






25. Monitors personal exposure to radiation






26. Safe Operating Procedures

28. Lead equivalent for apron






29. The effective focal spot is approximately 1/3 the size of the actual focal spot






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






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






32. The type of collimator that we have here






33. What is the term for an unknown cause






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






35. Is the most common artifact in radiography






36. With what kind of typical film do we get 95% exposure due to visible light and 5% is due to the x-rays directly






37. If the kVp is increased by 15% - the density is doubled






38. The 2 types of collimators are






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

45. Rotating anode






46. Between density and kVp






47. They don't move - they're found in dental units and portable units - cannot withstand the heat produced from large units
