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. Cassettes can be made of.....Which is the type here - or they can be made of magnesium - vinyl - etc






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






3. Extra pain is also called






4. What type of films need a lot more x-ray exposure and more time to expose them






5. Are produced when electrons are slowed down or stopped by atoms in the target area where they are aimed






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






7. The smaller the focal spot






8. Is the electrical current that heats the filament






9. A living animal - with tissue densities such as fat - muscle - fluid - and air






10. The 2 types of collimators are






11. If the thorax is greater than or equal to....you should use a grid






12. MAs for ANY part - when using a grid 3x= ?






13. Is the most common artifact in radiography






14. When a body part is greater than or equal to.....you should use a grid






15. 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)






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






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






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






19. There are......intensifying screens within a cassette






20. The greater the number of electrons released






21. Between density and mAs






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






23. What is one of the most common area of occurance for spinal problems (15% dobermans)






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






25. What type of bone tumors started elsewhere and spread to the location it was found






26. For bladder cystography - we use what contrast material instead of barium






27. Affects both density and contrast






28. Redness of the skin






29. The picture formed after the film has been exposed to x-rays and then processed into a visible image.






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






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






32. Incorrect grid focus is one reason for






33. MAs for abdomen (standard mAs) x=?






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






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






36. Increased crystal size.....






37. Can cause damage to living cells through the process of excitation or ionization of electrons in the orbits around atoms






38. Increase what value to penetrate thick body parts






39. Dislocations or separations






40. What spinal problem do doberman's get






41. General purpose film - forgiving






42. These screens are the most common type - they give good resolution with relatively low exposure






43. NYSVMS Facility Accreditation Standards






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






45. The layer of the film where the action occurs






46. MAs for chest 1/2x =?






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






48. To double the density






49. What gives off 4 times the amount of light photons than does the calcium tungstate (it gives off green light)






50. Within the collimator outlines just how much is collimated
