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. Loss of movement in legs (front and/or back)






2. A layer of intensifying screen that reflects the light from the phosphor layer toward the film






3. 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)






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






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






6. The type of collimator that we have here






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






8. 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






9. They don't move - they're found in dental units and portable units - cannot withstand the heat produced from large units






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






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






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






13. What are the 2 types of anodes






14. Is to the right - it produces the electrons






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






16. AgBr + light =






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






18. Rotating anode






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






20. Is on the anode and is angled at approximately 20 degrees from vertical






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






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






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






24. What must have little or no 'afterglow'






25. The smaller the focal spot






26. A clear protective layer on radiographic film






27. Weakness






28. What needs to have high levels of x-ray absorbtion






29. Calcium tungstate - rare earth elements






30. NYSVMS Facility Accreditation Standards






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






32. If the kVp is too high






33. Bone infection - also known as spondylitis






34. General purpose film - forgiving






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






36. Less forgiving - high contrast - cannot tolerate changes in exposure or processing






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






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






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






40. Has a negative charge






41. If the kVp is too low






42. Increase what value to penetrate thick body parts






43. Affects both density and contrast






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






45. What type of cystogram uses air and hypaque






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






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






48. What type of bone tumors started elsewhere and spread to the location it was found






49. Improper centering of grid is one reason for






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