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. Size film we use here






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






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






4. General purpose film - forgiving






5. What are the 2 types of anodes






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






7. This pertains to the size of the electron cloud and thus directly to the number of x-ray produced






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






9. The distance from the x-ray tube to the x-ray machine is the SID (source image distance) - or the FFD (also known as....)






10. Is on the anode and is angled at approximately 20 degrees from vertical






11. Is the electrical current that heats the filament






12. Incorrect grid focus is one reason for






13. AgBr + light =






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






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






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






17. The type of collimator that we have here






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






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






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






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






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






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






24. 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






25. Loss of movement in legs (front and/or back)






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






27. A device that moves the grid back and forth under the table. it helps to prevent grid lines from showing






28. Amount of radiation a person can recieve in a calendar year






29. Lead equivalent for thyroid sheild






30. Negative contrast agents appear what color on a radiograph






31. Monitors personal exposure to radiation






32. Rotating anode






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






34. MAs for chest 1/2x =?






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






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






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






38. Infection of a disk - or bone near it






39. With this procedure - no x-ray film is involved at all






40. Safe Operating Procedures






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






42. Ideally is very small






43. If perforation is suspected - what compound do we use when radiographing






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






45. This is inversely proportional to screen speed






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






47. Pigments tend to decrease the lateral spread of light so there is increased detail






48. Legally - a non-pregnant woman is required to hold a HBC dog for radiographs in NYS






49. Must change if the FFD changes






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