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






2. A clear protective layer on radiographic film






3. What type of cystogram uses air and hypaque






4. Screens are classified according to






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






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






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






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






9. Grid helps reduce the amount of......






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






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






12. Improper centering of grid is one reason for






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






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






17. DJD is also called






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






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






20. An invisible image on the x-ray film Which becomes visible after it has been processed in the manual or automatic processor






21. What spinal problem do doberman's get






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






23. X-ray machines come with a set one - we cannot adjust it






24. 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






25. Ideally is very small






26. Increase what value to penetrate thick body parts






27. We are supposed to use a grid if the abdomen is greater than or equal to......






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






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






30. The type of collimator that we have here






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






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






33. Negative contrast agents appear what color on a radiograph






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






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






36. Calcium tungstate - rare earth elements






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






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






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






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






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






42. In which processing solution do unionized (green) AgBr crystals get removed from the film






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






44. Has a positive charge






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






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






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






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






49. Weakness






50. Between density and mAs
