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. 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)






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






3. Rotating anode






4. Is the most common artifact in radiography






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






6. Is to the right - it produces the electrons






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






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






9. What spinal problem do doberman's get






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






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






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






13. The layer of the film where the action occurs






14. Lead equivalent for thyroid sheild






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






16. The shorter the wavelength of the x-ray - the more powerful the x-ray is






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






18. MAs for chest 1/2x =?






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






20. NYSVMS Facility Accreditation Standards






21. Body cells affected - damage seen during lifetime of creature - can be immediate or cummulative






22. Types of grids






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






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






25. Screens are classified according to






26. Is the measurement for the maximum energy available at that setting






27. Positive contrast agents appear what color on a radiograph






28. With the heel effect - more x-rays tend to be in the beam toward this end of the tube






29. What is the term for an unknown cause






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






31. A lightproof encasement designed to hold x-ray film and intensifying screens in close contact






32. An invisible image on the x-ray film Which becomes visible after it has been processed in the manual or automatic processor






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






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






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






36. To double the density






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






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






39. If the kVp is too low






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






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






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






43. Gelatinous center of disk - pinches spinal cord to cause herniated disk






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






45. The type of collimator that we have here






46. This number in santes' rule refers to the distance the x-ray tube is from the x-ray film






47. Give a 25% barium solution for upper GI series - and give At what dose?
