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.

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






18. Lead equivalent for thyroid sheild






19. Sheets of luminescent phosphor crystals bound together and mounted on a cardboard or plastic base






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






21. 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






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






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

38. Increase developing time and temp of developing fluid






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