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






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






3. What gives off 4 times the amount of light photons than does the calcium tungstate (it gives off green light)






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






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






6. Is on the anode and is angled at approximately 20 degrees from vertical






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






8. With what kind of typical film do we get 95% exposure due to visible light and 5% is due to the x-rays directly






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






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






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






12. Bone infection - also known as spondylitis






13. Is the most common artifact in radiography






14. Film with: high detail - minimal graininess - increased exposure






15. Is the electrical current that heats the filament






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






17. The smaller the focal spot






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






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






20. If the kVp is too low






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






22. What type of film has no screens or film cassettes






23. The effective focal spot is only 1/3 the size of the actual focal spot. this is called the






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






25. We should always try and stay How many feet from our x-ray machine






26. To utilize this - you position the thickest part of the animal towards the cathode end of the x-ray tube






27. Is the density difference between 2 adjacent areas on a radiograph






28. A clear protective layer on radiographic film






29. Extra vertebrae - scoliosis - fused vertebrae are all examples of






30. Screens are classified according to






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






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






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






34. Measures the power of penetrability (quality) of the x-rays produced






35. 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






36. The 2 types of collimators are






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






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






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






40. General purpose film - forgiving






41. The effective focal spot is approximately 1/3 the size of the actual focal spot






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






43. The type of collimator that we have here






44. Weakness






45. Lead equivalent for apron






46. A lightproof encasement designed to hold x-ray film and intensifying screens in close contact






47. If there's no object in the way of an x-ray - the picture would be






48. Is the source of electrons






49. If you use an mA of 300 - What time fraction must i use to get an mAs of 10?






50. Safe Operating Procedures
