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






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






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






4. Has a negative charge






5. Improper centering of grid is one reason for






6. MAs for chest 1/2x =?






7. Increase what value to penetrate thick body parts






8. Rotating anode






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






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






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






12. This is inversely proportional to screen speed






13. KVp=(2x thickness of body part in cm) + 40

14. Negative contrast agents appear what color on a radiograph






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






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






17. What is the name for the cartilage flap in the shoulder joint that has broken free and is floating around in the joint fluid






18. X-ray machines come with a set one - we cannot adjust it






19. Faster screens/less detail; slower screens/more detail






20. When the AgBr reacts and ionizes with light or x-rays - than at this point - What is on the film is known as the






21. Is the device which restricts (narrows) the beam of x-rays as they leave the x-ray machine






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






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






24. This number in santes' rule refers to the distance the x-ray tube is from the x-ray film






25. Another result of the 20 degree angling






26. The type of collimator that we have here






27. The 2 types of collimators are






28. What are the 2 types of anodes






29. The back of the cassette is made of lead to decrease....






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






31. Why do we not give atropine with a contrast radiograph






32. Safe Operating Procedures






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






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






35. Collimator






36. NYSVMS Facility Accreditation Standards






37. Film with silver crystals that is more sensitive to fluorescent light emitted from intensifying screens than to ionizing radiation






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






39. Body cells affected - damage seen during lifetime of creature - can be immediate or cummulative






40. Is the measurement for the maximum energy available at that setting






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






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






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. Increased thickness of this leads to increased x-ray absorption and increased visible light emission from the crystals






45. Radiographic signs dont always agree with what






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






47. If there's metal in the way of an x-ray - than no x-rays will get through and that part would be






48. Has a positive charge






49. Ideally is very small






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