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. A clear protective layer on radiographic film






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






3. When doing a lateral radiograph of the thorax/chest - the x-ray beam should be centered over what specific anatomical landmark






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






5. 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






6. The greater the number of electrons released






7. Incorrect grid focus is one reason for






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






9. Is the source of electrons






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






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






12. Is to the right - it produces the electrons






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






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






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






16. What is the term for an unknown cause






17. Screens are classified according to






18. If the kVp is too high






19. If the kVp is too low






20. 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






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






22. Is influenced by quantity of x-rays(mAs) - quality of x-rays (kVp) - type and thickness of tissue being x-rayed






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






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






25. What must have little or no 'afterglow'






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






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






28. Infection of a disk - or bone near it






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






30. If the x-ray tube is not 36-40 inches from the grid - this is called the






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






32. The shorter the wavelength of the x-ray - the more powerful the x-ray is






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






34. In the dark room - the safe light (red light) needs to be at least how far away from the loading bench






35. Has a filament made of tungsten - due to the high melting point






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






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






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






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






40. NYSVMS Facility Accreditation Standards






41. Slowly growing dividing cells are the most sensitive to the effects of ionizing radiaton






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






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






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






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






46. Within the collimator outlines just how much is collimated






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






48. Rotating anode






49. What are the 2 types of anodes






50. Collimator
