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. Means more electrons will be released from the filament and directed at the anode






2. 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






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






4. Rotating anode






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






6. What is the difference between fluoroscopy and a regular radiograph






7. A layer of intensifying screen that reflects the light from the phosphor layer toward the film






8. Must be radiolucent






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






10. Less forgiving - high contrast - cannot tolerate changes in exposure or processing






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






12. Ideally is very small






13. A...is a series of lead strips on edge which only allow the primary x-rays - which are traveling in straight lines - reach the film






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






15. Between density and kVp






16. If the x-ray tube is not 36-40 inches from the grid - this is called the






17. Refers to the 'blackness' of a radiograph






18. The effective focal spot is only 1/3 the size of the actual focal spot. this is called the






19. The x-ray machine we've been using has a rotating anode






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






21. To double the density






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






23. Aluminum filter






24. Increased crystal size.....






25. 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






26. What type of bone tumors started in the location they were first found






27. General purpose film - forgiving






28. The greater the number of electrons released






29. Is the electrical current that heats the filament






30. Calcium tungstate - rare earth elements






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






32. The layer of the film where the action occurs






33. Increased thickness of this leads to increased x-ray absorption and increased visible light emission from the crystals






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






35. Radiographic signs dont always agree with what






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






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






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






39. 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)






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






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






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






43. What type of film has no screens or film cassettes






44. What type of bone tumors started elsewhere and spread to the location it was found






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






46. Screen speed is.....to the exposure required to cause it to flouresce






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






48. Lead equivalent for apron






49. Longer wavelengths of electromagnetic radiation have more penetrating power






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