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.

17. When more electrons hit the focal spot on the anode






18. Positive contrast agents appear what color on a radiograph






19. With the heel effect - more x-rays tend to be in the beam toward this end of the tube






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






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






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






23. Increase mAs and kVp in order to...






24. Is influenced by quantity of x-rays(mAs) - quality of x-rays (kVp) - type and thickness of tissue being x-rayed

30. Affects both density and contrast






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






32. 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






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






34. Has a positive charge






35. 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






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

41. These cells are the most sensitive to radiation






42. Give a 25% barium solution for upper GI series - and give At what dose?






43. 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






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