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.

6. A lightproof encasement designed to hold x-ray film and intensifying screens in close contact






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






8. On a lateral view of the chest the aorta is dorsal to the caudal vena cava






9. The efficiency of this reflects light made by phosphors back towards the film






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






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






12. Screens are classified according to






13. When more electrons hit the focal spot on the anode






14. Has a negative charge






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






16. This is inversely proportional to screen speed






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






18. Infection of a disk - or bone near it






19. Give a 25% barium solution for upper GI series - and give At what dose?






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






21. Between density and mAs






22. The greater the number of electrons released






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






24. Monitors personal exposure to radiation






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






26. 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

43. To double the density






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






45. Size film we use here






46. Ideally is very small
