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.

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






12. The greater the number of electrons released






13. Weakness






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






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






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






17. The efficiency of this reflects light made by phosphors back towards the film






18. Is responsible for the number or quantity of x-rays






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






20. The electrical current sent through the filament to cause this electron release is called






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






22. A...is a series of lead strips on edge which only allow the primary x-rays - which are traveling in straight lines - reach the film






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






24. The effective focal spot is approximately 1/3 the size of the actual focal spot






25. Film with silver crystals that is more sensitive to fluorescent light emitted from intensifying screens than to ionizing radiation






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






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






28. This is inversely proportional to screen speed






29. On a lateral view of the chest the aorta is dorsal to the caudal vena cava






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






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






32. Can cause damage to living cells through the process of excitation or ionization of electrons in the orbits around atoms






33. Is to the left - electrons bounce off it at a 20 degree angle






34. AgBr + x-rays =






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






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






37. These screens have increased definition/detail - need to have increased radiation exposure






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






39. Extra vertebrae - scoliosis - fused vertebrae are all examples of






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