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. Film that is more sensitive to ionizing radiation than to fluorescent light

3. Radiograph of a dogs skeleton has a long scale of contrast






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






5. 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






6. This stage of pregnancy is the most dangerous for the fetus






7. What type of bone tumors started elsewhere and spread to the location it was found






8. If barium leaks into the abdomen or lungs - it can cause what






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






10. Calcium 'bridges' between adjacent vertebrae






11. Between density and kVp






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






13. Increase developing time and temp of developing fluid






14. Another result of the 20 degree angling






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






16. In the dark room - the safe light (red light) needs to be at least how far away from the loading bench






17. Types of grids






18. When the AgBr reacts and ionizes with light or x-rays - than at this point - What is on the film is known as the






19. This is inversely proportional to screen speed






20. An invisible image on the x-ray film Which becomes visible after it has been processed in the manual or automatic processor






21. MAs for bone views (pelvis - skull - spine) 2x =?






22. The tendency of a luminescent compound to continue to give off light after x-radiation has stopped






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






24. Incorrect grid focus is one reason for






25. The shorter the wavelength of the x-ray - the more powerful the x-ray is






26. Within the collimator outlines just how much is collimated






27. X-ray gloves have to have....of lead equivalent






28. Calcium tungstate - rare earth elements






29. Measures the power of penetrability (quality) of the x-rays produced






30. 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






31. What is the term for the spotty appearance on the film due to the large crystals in the screens






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






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






34. This gives you the desired mAs - and it gives less time for your patient to move






35. Faster screens/less detail; slower screens/more detail

37. Must change if the FFD changes






38. AgBr + x-rays =






39. When this is exposed to x-rays - it will absorb photons (quanta) and give off photons of visible light which the film is sensitive to (give off blue light)






40. Gelatinous center of disk - pinches spinal cord to cause herniated disk






41. Redness of the skin






42. Sheets of luminescent phorphor crystals on a cardboard or plastic base






43. The focused grid is upside down - is one reason for






44. Is the electrical current that heats the filament






45. Ideally is very small






46. MAs for abdomen (standard mAs) x=?






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






48. Bone - lymphatic cells - epitheilial - and hemopoietic cells are also what kind of cell?
