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 device that moves the grid back and forth under the table. it helps to prevent grid lines from showing






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






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






4. The smaller the focal spot






5. Is the device which restricts (narrows) the beam of x-rays as they leave the x-ray machine






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






7. Positive contrast agents appear what color on a radiograph






8. NYSVMS Facility Accreditation Standards






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






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






11. If the thorax is greater than or equal to....you should use a grid






12. Is to the right - it produces the electrons






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






14. Dislocations or separations






15. Are produced when electrons are slowed down or stopped by atoms in the target area where they are aimed






16. 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)






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






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






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






20. Extra pain is also called






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






22. Has a positive charge






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






24. We are supposed to use a grid if the abdomen is greater than or equal to......






25. Types of grids






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






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






28. Between density and kVp






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






30. Screens are classified according to






31. Improper centering of grid is one reason for






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






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






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






35. 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






36. Sheets of luminescent phorphor crystals on a cardboard or plastic base






37. Types of cell damage






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






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






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






41. Old mAs x (new FFD)2 divided by (old FFD)2






42. Is the most common artifact in radiography






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






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






45. Affects both density and contrast






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






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






48. The greater the number of electrons released






49. Incorrect grid focus is one reason for






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