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






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






3. Weakness






4. Infection of a disk - or bone near it






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

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






7. When the AgBr reacts and ionizes with light or x-rays - than at this point - What is on the film is known as the






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






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






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






11. If the kVp is too low






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






13. X-ray machines come with a set one - we cannot adjust it






14. What must have little or no 'afterglow'






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






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






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






18. There are......intensifying screens within a cassette






19. Increase developing time and temp of developing fluid






20. Negative contrast agents appear what color on a radiograph






21. Safe Operating Procedures






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






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






24. Affects both density and contrast






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






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






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






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






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






30. The electrical current sent through the filament to cause this electron release is called






31. DJD is also called






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






33. Distance from the grid to the x-ray tube (36-40 inches)






34. Is the electrical current that heats the filament






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






36. This stage of pregnancy is the most dangerous for the fetus






37. What is one of the most common areas of occurance for spinal problems ( 85% dachshunds)






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






39. Slowly growing dividing cells are the most sensitive to the effects of ionizing radiaton






40. Between density and kVp






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






42. MAs for extremities






43. Increased crystal size.....






44. The layer of the film where the action occurs






45. The mAs has to do with the power of the x-rays produced






46. 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






47. Longer wavelengths of electromagnetic radiation have more penetrating power






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






49. Ideally is very small






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