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. This is inversely proportional to screen speed






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






3. This pertains to the size of the electron cloud and thus directly to the number of x-ray produced






4. Weakness






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






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






7. What are the 2 types of anodes






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






9. General purpose film - forgiving






10. Longer wavelengths of electromagnetic radiation have more penetrating power






11. Affects both density and contrast






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






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






14. Collimator






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






16. Is the source of electrons






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






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






19. What type of cystogram uses air and hypaque






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






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






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






23. 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






24. If the kVp is too high






25. Film that is more sensitive to ionizing radiation than to fluorescent light






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






27. The greater the number of electrons released






28. Legally - a non-pregnant woman is required to hold a HBC dog for radiographs in NYS






29. The layer of the film where the action occurs






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






32. A device that moves the grid back and forth under the table. it helps to prevent grid lines from showing






33. Monitors personal exposure to radiation






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






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






36. 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






37. MAs for chest 1/2x =?






38. A grid must be used on the chest if it's 11cm thick






39. Bone infection - also known as spondylitis






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






41. Rotating anode






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






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






44. Animal has broken femur - it's ideal to have How many radiographs for diagnostic purposes






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






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






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






48. The 2 types of collimators are






49. What must have little or no 'afterglow'






50. With this procedure - no x-ray film is involved at all
