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.

15. What spinal problem do doberman's get






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






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






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






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






20. MAs for chest 1/2x =?






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






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






23. Distance from the grid to the x-ray tube (36-40 inches)






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






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






26. To double the density






27. Size film we use here






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






29. Is the source of electrons






30. What is the term for when the animal's bowel engulfs a piece of bowel distal to it - causing blockage






31. Must change if the FFD changes






32. Bone infection - also known as spondylitis






33. Types of cell damage






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






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






36. AgBr + x-rays =






37. Increase what value to penetrate thick body parts






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






39. Hairloss or baldness






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






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






42. The 2 types of collimators are






43. Longer wavelengths of electromagnetic radiation have more penetrating power






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






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






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