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.

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






10. Redness of the skin






11. Safe Operating Procedures






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






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






14. Lead equivalent for apron






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






16. Affects both density and contrast






17. The 2 types of collimators are






18. Types of cell damage






19. Increased crystal size.....






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






21. The picture formed after the film has been exposed to x-rays and then processed into a visible image.






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






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






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






25. Improper centering of grid is one reason for






26. A...is a series of lead strips on edge which only allow the primary x-rays - which are traveling in straight lines - reach the film






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






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






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






30. What type of films need a lot more x-ray exposure and more time to expose them






31. Between density and mAs






32. What type of film gives more detailed radiographs but more exposure to everyone involved? (commonly used as dental film - or for extremities)






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






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






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






36. Increase developing time and temp of developing fluid






37. DJD is also called






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






39. A type of electromagnetic radiation which have a shorter wavelength than visible light






40. A grid must be used on the chest if it's 11cm thick






41. These screens are high speed - they decrease exposure - poorer detail - able to penetrate thicker areas






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






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






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






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






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






47. Weakness






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






49. Is to the right - it produces the electrons






50. There are......intensifying screens within a cassette
