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. What type of films need a lot more x-ray exposure and more time to expose them






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






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






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






5. Sheets of luminescent phorphor crystals on a cardboard or plastic base






6. The greater the number of electrons released






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






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






9. MAs for chest 1/2x =?






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






11. MAs for ANY part - when using a grid 3x= ?






12. Hairloss or baldness






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






14. Film with silver crystals that is more sensitive to fluorescent light emitted from intensifying screens than to ionizing radiation






15. An abdominal radiograph should be taken at the peak of expiration






16. Affects both density and contrast






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






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






19. Has a negative charge






20. Size film we use here






21. Tilting of the tube or grid is one reason for






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






23. What type of bone tumors started in the location they were first found






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






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






26. The type of collimator that we have here






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






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






29. 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






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






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






32. MAs for abdomen (standard mAs) x=?






33. These cells are the most sensitive to radiation






34. What is the name for the cartilage flap in the shoulder joint that has broken free and is floating around in the joint fluid






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






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






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






38. Compound of silver and bromine - chlorine - or iodine - all of which are in the halogen group of elements






39. Longer wavelengths of electromagnetic radiation have more penetrating power






40. Infection of a disk - or bone near it






41. The 2 types of collimators are






42. We should always try and stay How many feet from our x-ray machine






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






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

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






46. Does move - has disks that rotate at high speeds - this helps spread out the heat that's produced as the electrons hit the focal spot






47. Collimator






48. Faster screens/less detail; slower screens/more detail






49. DJD is also called






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