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. The mAs has to do with the power of the x-rays produced






2. Is the device which restricts (narrows) the beam of x-rays as they leave the x-ray machine






3. This gives you the desired mAs - and it gives less time for your patient to move






4. AgBr + x-rays =






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






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

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






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






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






10. The x-ray machine we've been using has a rotating anode






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






12. The 2 types of collimators are






13. Means more electrons will be released from the filament and directed at the anode






14. Infection of a disk - or bone near it






15. This stage of pregnancy is the most dangerous for the fetus






16. Types of grids






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






18. If there's bone in the way of an x-ray -. those parts would be






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






20. These crystals will turn white/clear when processing film






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






22. A clear protective layer on radiographic film






23. Rotating anode






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






25. Lung tissue appears black (radiolucent) on a radiograph






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






27. Film that is more sensitive to ionizing radiation than to fluorescent light






28. MAs for extremities






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






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






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






32. With what kind of typical film do we get 95% exposure due to visible light and 5% is due to the x-rays directly






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






34. They don't move - they're found in dental units and portable units - cannot withstand the heat produced from large units






35. Lead equivalent for thyroid sheild






36. Calcium 'bridges' between adjacent vertebrae






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






38. Safe Operating Procedures






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






40. If there's metal in the way of an x-ray - than no x-rays will get through and that part would be






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






42. Weakness






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






44. Calcium tungstate - rare earth elements






45. What must have little or no 'afterglow'






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






47. Is the electrical current that heats the filament






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






49. AgBr + light =






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