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 processing film - the black areas are made of






2. Aluminum filter






3. Types of grids






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






5. Increase what value to penetrate thick body parts






6. This is inversely proportional to screen speed






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






8. Redness of the skin






9. KVp=(2x thickness of body part in cm) + 40

10. Rotating anode






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






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






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






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






15. If there's far or muscle in the way of an x-ray - those parts would be






16. The layer of the film where the action occurs






17. Extra pain is also called






18. Distance from the grid to the x-ray tube (36-40 inches)






19. NYSVMS Facility Accreditation Standards






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






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






22. 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)






23. Radiographic signs dont always agree with what






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






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






26. What are the 2 types of anodes






27. These cells are the most sensitive to radiation






28. Why do we not give atropine with a contrast radiograph






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






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






31. Has a negative charge






32. General purpose film - forgiving






33. Between density and kVp






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






35. Extra vertebrae - scoliosis - fused vertebrae are all examples of






36. Is the density difference between 2 adjacent areas on a radiograph






37. Collimator






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






39. Is to the left - electrons bounce off it at a 20 degree angle






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






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






42. What type of film gives more detailed radiographs but more exposure to everyone involved? (commonly used as dental film - or for extremities)






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






44. Safe Operating Procedures






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






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






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






48. What needs to have high levels of x-ray to light conversion with the correct energy and color for the type of film used






49. What must have little or no 'afterglow'






50. Sheets of luminescent phosphor crystals bound together and mounted on a cardboard or plastic base
