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. Infection of a disk - or bone near it






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






3. What is one of the most common area of occurance for spinal problems (15% dobermans)






4. Radiograph of a dogs skeleton has a long scale of contrast






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






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






7. What is the difference between fluoroscopy and a regular radiograph






8. Types of cell damage






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






10. The type of collimator that we have here






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






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






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






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. AgBr + light =






16. 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






17. This is inversely proportional to screen speed






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






19. Calcium 'bridges' between adjacent vertebrae






20. Hairloss or baldness






21. Must change if the FFD changes






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






23. Has a positive charge






24. Refers to the 'blackness' of a radiograph






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






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






27. Has a negative charge






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






29. Grid helps reduce the amount of......






30. Types of grids






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






32. Is the source of electrons






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






34. Affects both density and contrast






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






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






37. With the heel effect - more x-rays tend to be produced toward the cathode end






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






39. 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






40. For bladder cystography - we use what contrast material instead of barium






41. Increase what value to penetrate thick body parts






42. Is to the right - it produces the electrons






43. Crystals + x-rays = ?






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






45. Another result of the 20 degree angling






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






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






48. The tendency of a luminescent compound to continue to give off light after x-radiation has stopped






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






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