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. Is the most common artifact in radiography






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






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






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






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






6. The efficiency of this reflects light made by phosphors back towards the film






7. We are supposed to use a grid if the abdomen is greater than or equal to......






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






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






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






11. Bone infection - also known as spondylitis






12. Increase developing time and temp of developing fluid






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






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






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






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






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






18. The layer of the film where the action occurs






19. What are the 2 types of anodes






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






21. Dislocations or separations






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






23. These screens have increased definition/detail - need to have increased radiation exposure






24. Increased crystal size.....






25. Lead equivalent for apron






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






27. If there's bone in the way of an x-ray -. those parts would be






28. What must have little or no 'afterglow'






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






30. Collimator






31. Growth - gonadal - neoplastic - and metabolically active cells are what kind of cells






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






33. Is the electrical current that heats the filament






34. X-ray gloves have to have....of lead equivalent






35. Lung tissue appears black (radiolucent) on a radiograph






36. Calcium tungstate - rare earth elements






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






38. Is determined by the ratio of the height of the lead strips to the distance between them






39. If there's far or muscle in the way of an x-ray - those parts would be






40. Types of cell damage






41. Another result of the 20 degree angling






42. MAs for bone views (pelvis - skull - spine) 2x =?






43. Screen speed is.....to the exposure required to cause it to flouresce






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






45. Most commonly used film - compromise between graininess and speed (detail)






46. When.....collide with the anode - 99% of energy is released in the form of heat - and 1% of energy is in the form of x-rays






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






48. Is the source of electrons






49. AgBr + light =






50. 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
