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. Types of cell damage






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






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






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






5. This is caused by mutations in gonadal cells - not seen until offspring are produced - mutations are not always bad






6. Ideally is very small






7. The type of collimator that we have here






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






9. These screens are the most common type - they give good resolution with relatively low exposure






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






11. If perforation is suspected - what compound do we use when radiographing






12. NYSVMS Facility Accreditation Standards






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






14. Screens are classified according to






15. What is the term for the spotty appearance on the film due to the large crystals in the screens






16. Extra pain is also called






17. Between density and mAs






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






19. Incorrect grid focus is one reason for






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






21. Hairloss or baldness






22. Faster screens/less detail; slower screens/more detail






23. Is responsible for the number or quantity of x-rays






24. The 2 types of collimators are






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






26. Is to the left - electrons bounce off it at a 20 degree angle






27. Is to the right - it produces the electrons






28. Can cause damage to living cells through the process of excitation or ionization of electrons in the orbits around atoms






29. 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






30. Aluminum filter






31. 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






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






33. To double the density






34. Grid helps reduce the amount of......






35. When processing film - the black areas are made of






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






37. Calcium tungstate - rare earth elements






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






39. A clear protective layer on radiographic film






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






41. Refers to the 'blackness' of a radiograph






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






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






44. What is the term for a negative contrast cystogram where we inject air






45. What is the term for an unknown cause






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






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






48. Give a 25% barium solution for upper GI series - and give At what dose?






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






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