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 high






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






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






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






5. AgBr + x-rays =






6. Rotating anode






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






8. Crystals + x-rays = ?






9. To double the density






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






11. The tendency of a luminescent compound to continue to give off light after x-radiation has stopped






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






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






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






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






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






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






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






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






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






21. We ideally take a radiograph of the abdomen at the peak of inspiration






22. If there's bone in the way of an x-ray -. those parts would be






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






24. When a body part is greater than or equal to.....you should use a grid






25. Types of grids






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






27. MAs for extremities






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






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






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






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






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






33. The 2 types of collimators are






34. 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






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






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






37. When.....collide with the anode - 99% of energy is released in the form of heat - and 1% of energy is in the form of x-rays






38. Safe Operating Procedures






39. The smaller the focal spot






40. Must increase.....to compensate for x-ray absorption by the grid. (we triple our mAs)






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






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






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






44. To utilize this - you position the thickest part of the animal towards the cathode end of the x-ray tube






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






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






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






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






49. 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)






50. Is the most common artifact in radiography
