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. Radiographic signs dont always agree with what






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






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






4. Areas on film that should be black but come out grey - due to storage






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






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






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






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






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






10. Another result of the 20 degree angling






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






12. Ideally is very small






13. Types of grids






14. Is the source of electrons






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






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






17. General purpose film - forgiving






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






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






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






21. Longer wavelengths of electromagnetic radiation have more penetrating power






22. Infection of a disk - or bone near it






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






24. Screens are classified according to






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






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






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






28. NYSVMS Facility Accreditation Standards






29. Size film we use here






30. A living animal - with tissue densities such as fat - muscle - fluid - and air






31. The electrical current sent through the filament to cause this electron release is called






32. Between density and mAs






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






34. Types of cell damage






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






36. The 2 types of collimators are






37. AgBr + light =






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






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






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






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






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






43. The type of collimator that we have here






44. Aluminum filter






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






46. If the x-ray tube is not 36-40 inches from the grid - this is called the






47. Incorrect grid focus is one reason for






48. MAs for bone views (pelvis - skull - spine) 2x =?






49. Negative contrast agents appear what color on a radiograph






50. Must change if the FFD changes
