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 type of film has no screens or film cassettes






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






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






4. General purpose film - forgiving






5. Refers to the 'blackness' of a radiograph






6. With this procedure - no x-ray film is involved at all






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






8. A clear protective layer on radiographic film






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






10. Lead equivalent for apron






11. Increase developing time and temp of developing fluid






12. DJD is also called






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






14. Has a negative charge






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






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






17. 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






18. The greater the number of electrons released






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






20. Faster screens/less detail; slower screens/more detail






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






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






23. With what kind of typical film do we get 95% exposure due to visible light and 5% is due to the x-rays directly






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






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






26. What must have little or no 'afterglow'






27. Must be radiolucent






28. Increased thickness of this leads to increased x-ray absorption and increased visible light emission from the crystals






29. Tilting of the tube or grid is one reason for






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






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






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






33. The x-ray machine we've been using has a rotating anode






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






35. Crystals + x-rays = ?






36. Within the collimator outlines just how much is collimated






37. For bladder cystography - we use what contrast material instead of barium






38. The smaller the focal spot






39. Between density and mAs






40. 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






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






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






43. Radiograph of a dogs skeleton has a long scale of contrast






44. Incorrect grid focus is one reason for






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






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






47. If you use an mA of 300 - What time fraction must i use to get an mAs of 10?






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






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






50. Grid helps reduce the amount of......
