Radiology 2

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. How long are films fixed






2. when processing - two films overlap in the developer - but not in the fixer. How would the films appear






3. What Size film is 1 1/16 x 2 1/8






4. What is the bremsstrahlung radiation






5. What part of the x-ray machine is responsible for providing the electrons






6. When mounting a FMS - you notice that one film is blank. another film is dark - the teeth look strange - and it is difficult to determine What film it is. What do you think happened?






7. which dose of radiation is more biologically damaging






8. When looking at radiographs that were taken several years ago - you notice a brownish stain which makes interpretation difficult. What caused this?






9. when manually processing dental film - you notice the temp. has gotten warmer as the day progressed. How should the developing time be changed?






10. How many impulses are in .25 seconds






11. Film submerged totally in fixer but not in developer






12. you use an exposure time of 10 impulses. How many seconds is this






13. When taking a radiograph - you pull the end of the PID away from the patients face about 6 inches. How will this affect the radiographic image and patient exposure






14. What parts of the x-ray machine are included in the anode circuit






15. Mand lateral/canine anatomy






16. How is vertical angulation established with the paralleling technique






17. What is the optimum processing temp.






18. What is the max. permissable fose for radiation workers in systeme interventional units






19. What can be done to increase the life span of processing solutions






20. How does packet placement differ b/w bisecting and paralleling






21. when taking a radiograph - you pulls the cone out about 6 inches from the patient's face. What is the result






22. When viewing a periapical radiograph - you notice that the image of the tooth is extremely long and well defined; However the apices are missing. What technique was used to take the radiograph? What caused the roots to appear long?






23. What can be done to prevent air bubbles from being trapped on the surface of films during manual processing






24. How do you differentiate b/w max and mand molar when mounting






25. which anatomic feature is visible on a PANO - bu not on a PA






26. How does the reproductive capacity of a cell correlate with radiosensitivity






27. List the properties of x-rays






28. What Size film is 7/8 x 1 3/8






29. How can exposure to the operator be reduced






30. What is the earliest sign of radiation exposure






31. your film badge report sHows that you have received a small amt. of radiation. What should you do






32. How does exposure time for edentulous patients compare to dentulous patients






33. What Size film is used to take an occlusal radiograph of a 6 yr old child






34. How does kVp affect patient exposure






35. when taking a paralleling radiograph of a patient with palatal tori - Where is the film places






36. What type of film are rare earth screens paired with






37. What film is used to diagnose interproximal decay






38. What film would be used to locate a foreign body in the bucco-lingual relationship






39. How does exposure time differ b/w adults and children






40. The cells from most sensitive to least sensitive






41. Size film used for BW on adults






42. How often are BW taken on children with high risk






43. What does alara stand for






44. How long does film stay in the developer






45. What is characteristic radiation






46. Mand molar anatomy






47. What is the purpose of collimation






48. What is small doses of radiation given over a long period of time






49. How does radiation effect cells






50. What is the proper patient position for BW's?
