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. MAs for abdomen (standard mAs) x=?






2. What is the term for an unknown cause






3. What gives off 4 times the amount of light photons than does the calcium tungstate (it gives off green light)






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






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






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






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






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






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






10. Improper centering of grid is one reason for






11. Safe Operating Procedures






12. What must have little or no 'afterglow'






13. Dislocations or separations






14. Does move - has disks that rotate at high speeds - this helps spread out the heat that's produced as the electrons hit the focal spot






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






16. Bone - lymphatic cells - epitheilial - and hemopoietic cells are also what kind of cell?






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






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






19. Refers to the 'blackness' of a radiograph






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






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






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






23. Infection of a disk - or bone near it






24. Affects both density and contrast






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






26. Screens are classified according to






27. Areas on film that should be black but come out grey - due to storage






28. Extra vertebrae - scoliosis - fused vertebrae are all examples of






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






30. Increase what value to penetrate thick body parts






31. Increase mAs and kVp in order to...






32. Longer wavelengths of electromagnetic radiation have more penetrating power






33. DJD is also called






34. What type of cystogram uses air and hypaque






35. Compound of silver and bromine - chlorine - or iodine - all of which are in the halogen group of elements






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






37. AgBr + x-rays =






38. Weakness






39. What are the 2 types of anodes






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






41. Bone infection - also known as spondylitis






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






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






44. Pigments tend to decrease the lateral spread of light so there is increased detail






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






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






47. Is the electrical current that heats the filament






48. Increase developing time and temp of developing fluid






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






50. This is inversely proportional to screen speed
