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






2. The 2 types of collimators are






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






4. Outer layer of disk ( dries out and cracks and causes disk to herniate)






5. Is the most common artifact in radiography






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






7. If barium leaks into the abdomen or lungs - it can cause what






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






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






10. NYSVMS Facility Accreditation Standards






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






12. Infection of a disk - or bone near it






13. These screens are high speed - they decrease exposure - poorer detail - able to penetrate thicker areas






14. Affects both density and contrast






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






16. Increase what value to penetrate thick body parts






17. If the kVp is too high






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






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






20. What are the 2 types of anodes






21. Within the collimator outlines just how much is collimated






22. If the thorax is greater than or equal to....you should use a grid






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






24. Monitors personal exposure to radiation






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






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






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






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






29. Lead equivalent for apron






30. Extra pain is also called






31. A clear protective layer on radiographic film






32. MAs for extremities






33. Calcium 'bridges' between adjacent vertebrae






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






35. 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






36. Film with: ultra speed - grainier image - less exposure needed






37. The distance from the x-ray tube to the x-ray machine is the SID (source image distance) - or the FFD (also known as....)






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






39. A type of electromagnetic radiation which have a shorter wavelength than visible light






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






41. To double the density






42. When this is exposed to x-rays - it will absorb photons (quanta) and give off photons of visible light which the film is sensitive to (give off blue light)






43. If the kVp is too low






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






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






46. 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






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






48. Negative contrast agents appear what color on a radiograph






49. The exact area of the anode that the electrons hit






50. Has a negative charge
