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. Has a filament made of tungsten - due to the high melting point






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






4. The type of collimator that we have here






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






6. Is the source of electrons






7. White against black - like the x-ray of a plain skeleton






8. When doing a lateral radiograph of the thorax/chest - the x-ray beam should be centered over what specific anatomical landmark






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






10. Extra pain is also called






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






12. Is the most common artifact in radiography






13. MAs for ANY part - when using a grid 3x= ?






14. If perforation is suspected - what compound do we use when radiographing






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






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






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






18. Positive contrast agents appear what color on a radiograph






19. This is inversely proportional to screen speed






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






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






22. Bone infection - also known as spondylitis






23. Hairloss or baldness






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






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






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






27. What needs to have high levels of x-ray to light conversion with the correct energy and color for the type of film used






28. Must change if the FFD changes






29. Increase developing time and temp of developing fluid






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






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






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






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






34. Another result of the 20 degree angling






35. What is the term for an unknown cause






36. The 2 types of collimators are






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






38. Calcium 'bridges' between adjacent vertebrae






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






40. When processing film - the black areas are made of






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






42. The distance from the x-ray tube to the x-ray machine is the SID (source image distance) - or the FFD (also known as....)






43. Dislocations or separations






44. Incorrect grid focus is one reason for






45. What type of cystogram uses air and hypaque






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






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






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






49. Collimator






50. Between density and kVp
