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. DJD is also called






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






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






4. Safe Operating Procedures






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






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






7. Size film we use here






8. Extra vertebrae - scoliosis - fused vertebrae are all examples of






9. AgBr + light =






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






11. Collimator






12. Negative contrast agents appear what color on a radiograph






13. Within the collimator outlines just how much is collimated






14. What is the term for a negative contrast cystogram where we inject air






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






16. The efficiency of this reflects light made by phosphors back towards the film






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






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






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






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






21. For bladder cystography - we use what contrast material instead of barium






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






23. What type of cystogram uses air and hypaque






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






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






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






27. What is the term for an unknown cause






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






29. Refers to the 'blackness' of a radiograph






30. The greater the number of electrons released






31. Redness of the skin






32. Must be radiolucent






33. Crystals + x-rays = ?






34. What is the term for when the animal's bowel engulfs a piece of bowel distal to it - causing blockage






35. Has a negative charge






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






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






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






39. Can cause damage to living cells through the process of excitation or ionization of electrons in the orbits around atoms






40. Is to the right - it produces the electrons






41. A grid must be used on the chest if it's 11cm thick






42. This is caused by mutations in gonadal cells - not seen until offspring are produced - mutations are not always bad






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






44. What must have little or no 'afterglow'






45. With the heel effect - more x-rays tend to be produced toward the cathode end






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






47. Calcium 'bridges' between adjacent vertebrae






48. Is located in a focusing cup made of molybdenum which has a high melting point and helps to direct the electrons produced toward the cathode






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






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