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. The focused grid is upside down - is one reason for






2. Between density and mAs






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






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






5. 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






6. Increase developing time and temp of developing fluid






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






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






9. Loss of movement in legs (front and/or back)






10. This is inversely proportional to screen speed






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






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






13. Radiographic signs dont always agree with what






14. NYSVMS Facility Accreditation Standards






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






16. When a body part is greater than or equal to.....you should use a grid






17. What needs to have high levels of x-ray to light conversion with the correct energy and color for the type of film used






18. What type of film has the x-rays directly cause the latent image to be formed






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






20. Incorrect grid focus is one reason for






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






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






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






24. This is used to take 'real-time' radiographs - used a lot in horses






25. An abdominal radiograph should be taken at the peak of expiration






26. There are......intensifying screens within a cassette






27. Dislocations or separations






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






29. Crystals + x-rays = ?






30. Positive contrast agents appear what color on a radiograph






31. Monitors personal exposure to radiation






32. Lead equivalent for thyroid sheild






33. Collimator






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






35. Screens are classified according to






36. A layer of intensifying screen that reflects the light from the phosphor layer toward the film






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






38. What is the term for when the animal's bowel engulfs a piece of bowel distal to it - causing blockage






39. MAs for abdomen (standard mAs) x=?






40. The layer of the film where the action occurs






41. If the kVp is increased by 15% - the density is doubled






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






43. MAs for extremities






44. DJD is also called






45. Tilting of the tube or grid is one reason for






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

47. Gelatinous center of disk - pinches spinal cord to cause herniated disk






48. Sheets of luminescent phosphor crystals bound together and mounted on a cardboard or plastic base






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






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