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






2. Ideally is very small






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






4. With the heel effect - more x-rays tend to be produced toward the cathode end






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






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






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






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






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






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






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






12. Film that is more sensitive to ionizing radiation than to fluorescent light






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






14. Between density and kVp






15. Lead equivalent for thyroid sheild






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






17. Is to the right - it produces the electrons






18. Is the source of electrons






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






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






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






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






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






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






25. 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






26. Is the electrical current that heats the filament






27. Extra pain is also called






28. Collimator






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






30. Bone infection - also known as spondylitis






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






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






33. Outer layer of disk ( dries out and cracks and causes disk to herniate)






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






35. Monitors personal exposure to radiation






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






37. Means more electrons will be released from the filament and directed at the anode






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






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






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






41. Calcium 'bridges' between adjacent vertebrae






42. We ideally take a radiograph of the abdomen at the peak of inspiration






43. Measures the power of penetrability (quality) of the x-rays produced






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






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






46. Negative contrast agents appear what color on a radiograph






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






48. Has a negative charge






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






50. MAs for extremities
