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. What type of film has no screens or film cassettes

3. Affects both density and contrast






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

6. Extra pain is also called






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






8. Aluminum filter






9. 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

13. Has a positive charge






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






15. What is the term for an unknown cause






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






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






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

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






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






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






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






28. Redness of the skin






29. Has a negative charge






30. Safe Operating Procedures






31. Weakness

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






34. Between density and mAs






35. What must have little or no 'afterglow'






36. Another result of the 20 degree angling






37. An invisible image on the x-ray film Which becomes visible after it has been processed in the manual or automatic processor






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






39. What spinal problem do doberman's get






40. Between density and kVp






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






42. Collimator






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






44. Must change if the FFD changes






45. What type of bone tumors started in the location they were first found






46. The electrical current sent through the filament to cause this electron release is called






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






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






49. Crystals + x-rays = ?






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