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






2. This gives you the desired mAs - and it gives less time for your patient to move






3. Is to the right - it produces the electrons






4. This pertains to the size of the electron cloud and thus directly to the number of x-ray produced






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






6. What are the 2 types of anodes






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






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






9. Is the measurement for the maximum energy available at that setting






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






11. What is the term for an unknown cause






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






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






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






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






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

17. Redness of the skin






18. To double the density






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






20. The smaller the focal spot






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






22. What type of cystogram uses air and hypaque






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






24. What type of bone tumors started in the location they were first found






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






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






27. Calcium 'bridges' between adjacent vertebrae






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






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






30. An invisible image on the x-ray film Which becomes visible after it has been processed in the manual or automatic processor






31. Is the electrical current that heats the filament






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






33. If there's metal in the way of an x-ray - than no x-rays will get through and that part would be






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






35. What is the name for the cartilage flap in the shoulder joint that has broken free and is floating around in the joint fluid






36. What is one of the most common areas of occurance for spinal problems ( 85% dachshunds)






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






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






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






40. The mAs has to do with the power of the x-rays produced






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






42. Increase developing time and temp of developing fluid






43. If the kVp is too high






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






45. Body cells affected - damage seen during lifetime of creature - can be immediate or cummulative






46. Dislocations or separations






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






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






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






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