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

18. What type of cystogram uses air and hypaque






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






20. Is located in a focusing cup made of molybdenum which has a high melting point and helps to direct the electrons produced toward the cathode






21. A clear protective layer on radiographic film






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