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. Improper centering of grid is one reason for






2. Weakness






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






4. Types of grids






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






6. The exact area of the anode that the electrons hit






7. Has a negative charge






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






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






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






11. On a lateral view of the chest the aorta is dorsal to the caudal vena cava






12. Collimator






13. General purpose film - forgiving






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






15. Outer layer of disk ( dries out and cracks and causes disk to herniate)






16. Hairloss or baldness






17. The type of collimator that we have here






18. Dislocations or separations






19. What gives off 4 times the amount of light photons than does the calcium tungstate (it gives off green light)






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






21. Redness of the skin






22. Bone infection - also known as spondylitis






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






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






25. What type of film has the x-rays directly cause the latent image to be formed






26. When doing a lateral radiograph of the thorax/chest - the x-ray beam should be centered over what specific anatomical landmark






27. This is inversely proportional to screen speed






28. What must have little or no 'afterglow'






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






30. For bladder cystography - we use what contrast material instead of barium






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






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






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






34. When the density difference is great - there is






35. Size film we use here






36. Increase mAs and kVp in order to...






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

38. Most commonly used film - compromise between graininess and speed (detail)






39. NYSVMS Facility Accreditation Standards






40. A clear protective layer on radiographic film






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






42. If there's no object in the way of an x-ray - the picture would be






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






44. What needs to have high levels of x-ray absorbtion






45. 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






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






47. When a body part is greater than or equal to.....you should use a grid






48. Rotating anode






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






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