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






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






3. 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






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






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






6. Compound of silver and bromine - chlorine - or iodine - all of which are in the halogen group of elements






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






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






9. If the kVp is too high






10. 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






11. Is the measurement for the maximum energy available at that setting






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






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






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






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






16. NYSVMS Facility Accreditation Standards






17. What must have little or no 'afterglow'






18. Give a 25% barium solution for upper GI series - and give At what dose?






19. As this increases - the intensity of the x-ray beam decreases - so the beam intensity increases - and the mAs must decrease to compensate






20. What needs to have high levels of x-ray absorbtion






21. Extra pain is also called






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






23. Growth - gonadal - neoplastic - and metabolically active cells are what kind of cells






24. Calcium tungstate - rare earth elements






25. Is to the right - it produces the electrons






26. Film with: high detail - minimal graininess - increased exposure






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






28. Why do we not give atropine with a contrast radiograph






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






30. The greater the number of electrons released






31. A living animal - with tissue densities such as fat - muscle - fluid - and air






32. The back of the cassette is made of lead to decrease....






33. Most commonly used film - compromise between graininess and speed (detail)






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






35. Film with silver crystals that is more sensitive to fluorescent light emitted from intensifying screens than to ionizing radiation






36. What is the name for the cartilage flap in the shoulder joint that has broken free and is floating around in the joint fluid






37. To utilize this - you position the thickest part of the animal towards the cathode end of the x-ray tube






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






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






40. Tilting of the tube or grid is one reason for






41. Sheets of luminescent phosphor crystals bound together and mounted on a cardboard or plastic base






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






43. Redness of the skin






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






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






46. General purpose film - forgiving






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






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






49. If the kVp is too low






50. What specific part of the eye is cloudy with a cataract
