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






2. Dislocations or separations






3. Screens are classified according to






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






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






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






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






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






9. Radiograph of a dogs skeleton has a long scale of contrast






10. The exact area of the anode that the electrons hit






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






12. The picture formed after the film has been exposed to x-rays and then processed into a visible image.






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






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






15. Increased crystal size.....






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






17. If there's no object in the way of an x-ray - the picture would be






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






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






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






21. Has a positive charge






22. Longer wavelengths of electromagnetic radiation have more penetrating power






23. Aluminum filter






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






25. Outer layer of disk ( dries out and cracks and causes disk to herniate)

30. What is one of the most common area of occurance for spinal problems (15% dobermans)






31. Hairloss or baldness






32. Must be radiolucent






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






34. Weakness






35. AgBr + light =






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






37. What type of films need a lot more x-ray exposure and more time to expose them






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






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