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






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






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






4. 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






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






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






7. Calcium tungstate - rare earth elements






8. Safe Operating Procedures






9. Between density and kVp






10. Film with: ultra speed - grainier image - less exposure needed






11. These screens have increased definition/detail - need to have increased radiation exposure






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






13. Collimator






14. Weakness






15. These screens are the most common type - they give good resolution with relatively low exposure






16. The efficiency of this reflects light made by phosphors back towards the film






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






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






19. The focused grid is upside down - is one reason for






20. What must have little or no 'afterglow'






21. What is the term for when the animal's bowel engulfs a piece of bowel distal to it - causing blockage






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






23. If the kVp is too high






24. Is responsible for the number or quantity of x-rays






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






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






27. The 2 types of collimators are






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






29. The greater the number of electrons released






30. If you use an mA of 300 - What time fraction must i use to get an mAs of 10?






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






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






33. Negative contrast agents appear what color on a radiograph






34. When more electrons hit the focal spot on the anode






35. NYSVMS Facility Accreditation Standards






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






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






38. What is the term for the spotty appearance on the film due to the large crystals in the screens






39. Grid helps reduce the amount of......






40. If the grid is stationary - more lines that are finer are less apt to show up on a radiograph - this is called....






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






42. 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






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






44. Extra pain is also called






45. The effective focal spot is approximately 1/3 the size of the actual focal spot






46. If barium leaks into the abdomen or lungs - it can cause what






47. Is the source of electrons






48. Rotating anode






49. The layer of the film where the action occurs






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