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. Positive contrast agents appear what color on a radiograph






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






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






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






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






6. The effective focal spot is only 1/3 the size of the actual focal spot. this is called the






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






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






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






10. Animal has broken femur - it's ideal to have How many radiographs for diagnostic purposes






11. Weakness






12. Is only 1/3 the size of the actual focal spot






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






14. MAs for chest 1/2x =?






15. Types of cell damage






16. The focused grid is upside down - is one reason for






17. There are......intensifying screens within a cassette






18. This pertains to the size of the electron cloud and thus directly to the number of x-ray produced






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






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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






22. Areas on film that should be black but come out grey - due to storage






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






24. Screen speed is.....to the exposure required to cause it to flouresce






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






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






27. Within the collimator outlines just how much is collimated






28. Must be radiolucent






29. Calcium 'bridges' between adjacent vertebrae






30. These cells are the most sensitive to radiation






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






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






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






34. Body cells affected - damage seen during lifetime of creature - can be immediate or cummulative






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






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






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






38. Negative contrast agents appear what color on a radiograph






39. Measures the power of penetrability (quality) of the x-rays produced






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






41. A device that moves the grid back and forth under the table. it helps to prevent grid lines from showing






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






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






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






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






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






47. Crystals + x-rays = ?






48. Must increase.....to compensate for x-ray absorption by the grid. (we triple our mAs)






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






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