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 layer of the film where the action occurs






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






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






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






5. A lightproof encasement designed to hold x-ray film and intensifying screens in close contact






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






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






8. Are produced when electrons are slowed down or stopped by atoms in the target area where they are aimed






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






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






11. Hairloss or baldness






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






13. With the heel effect - more x-rays tend to be produced toward the cathode end






14. Old mAs x (new FFD)2 divided by (old FFD)2






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






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






17. Film with: high detail - minimal graininess - increased exposure






18. Redness of the skin






19. Calcium 'bridges' between adjacent vertebrae






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






21. General purpose film - forgiving






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






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






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






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






26. What type of film has no screens or film cassettes






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






28. Radiograph of a dogs skeleton has a long scale of contrast






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






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






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






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






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






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






35. Must be radiolucent






36. The tendency of a luminescent compound to continue to give off light after x-radiation has stopped






37. What is one of the most common areas of occurance for spinal problems ( 85% dachshunds)






38. Increase what value to penetrate thick body parts






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






40. To double the density






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






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






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






44. Rotating anode






45. Between density and mAs






46. What type of cystogram uses air and hypaque






47. A grid must be used on the chest if it's 11cm thick






48. Radiographic signs dont always agree with what






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






50. NYSVMS Facility Accreditation Standards
