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. Has a positive charge






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






3. With the heel effect - more x-rays tend to be in the beam toward this end of the tube






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






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






6. Has a negative charge






7. What are the 2 types of anodes






8. Must change if the FFD changes






9. Monitors personal exposure to radiation






10. Crystals + x-rays = ?






11. Extra pain is also called






12. If the grid is stationary - more lines that are finer are less apt to show up on a radiograph - this is called....






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






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






15. Must increase.....to compensate for x-ray absorption by the grid. (we triple our mAs)






16. Types of cell damage






17. We are supposed to use a grid if the abdomen is greater than or equal to......






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






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






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






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






22. When more electrons hit the focal spot on the anode






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

24. Affects both density and contrast






25. Positive contrast agents appear what color on a radiograph






26. If the kVp is too high






27. Is to the left - electrons bounce off it at a 20 degree angle






28. Increase what value to penetrate thick body parts






29. This is inversely proportional to screen speed






30. Redness of the skin






31. Within the collimator outlines just how much is collimated






32. General purpose film - forgiving






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






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






35. We ideally take a radiograph of the abdomen at the peak of inspiration






36. Pigments tend to decrease the lateral spread of light so there is increased detail






37. This number in santes' rule refers to the distance the x-ray tube is from the x-ray film






38. 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)






39. Is only 1/3 the size of the actual focal spot






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






41. Is influenced by quantity of x-rays(mAs) - quality of x-rays (kVp) - type and thickness of tissue being x-rayed






42. If the thorax is greater than or equal to....you should use a grid






43. What is one of the most common area of occurance for spinal problems (15% dobermans)






44. Animal has broken femur - it's ideal to have How many radiographs for diagnostic purposes






45. Calcium 'bridges' between adjacent vertebrae






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






47. The layer of the film where the action occurs






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






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






50. Is to the right - it produces the electrons
