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. If the kVp is too low






2. Cassettes can be made of.....Which is the type here - or they can be made of magnesium - vinyl - etc






3. Are produced when electrons are slowed down or stopped by atoms in the target area where they are aimed






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






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






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






7. Aluminum filter






8. Calcium tungstate - rare earth elements






9. Rotating anode






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






11. When.....collide with the anode - 99% of energy is released in the form of heat - and 1% of energy is in the form of x-rays






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






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






14. KVp=(2x thickness of body part in cm) + 40

15. 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






16. Monitors personal exposure to radiation






17. Collimator






18. Outer layer of disk ( dries out and cracks and causes disk to herniate)






19. Screens are classified according to






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






21. There are......intensifying screens within a cassette






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






23. The greater the number of electrons released






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






25. Lung tissue appears black (radiolucent) on a radiograph






26. Old mAs x (new FFD)2 divided by (old FFD)2






27. A type of electromagnetic radiation which have a shorter wavelength than visible light






28. 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)






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






30. Weakness






31. What is the term for an unknown cause






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






33. We should always try and stay How many feet from our x-ray machine






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






35. This pertains to the size of the electron cloud and thus directly to the number of x-ray produced






36. What type of film has the x-rays directly cause the latent image to be formed






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






38. If there's far or muscle in the way of an x-ray - those parts would be






39. Areas on film that should be black but come out grey - due to storage






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






41. This is used to take 'real-time' radiographs - used a lot in horses






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






43. Is the most common artifact in radiography






44. Is responsible for the number or quantity of x-rays






45. Bone infection - also known as spondylitis






46. Legally - a non-pregnant woman is required to hold a HBC dog for radiographs in NYS






47. These screens are high speed - they decrease exposure - poorer detail - able to penetrate thicker areas






48. Is determined by the ratio of the height of the lead strips to the distance between them






49. What type of film gives more detailed radiographs but more exposure to everyone involved? (commonly used as dental film - or for extremities)






50. When a body part is greater than or equal to.....you should use a grid
