You are responsible for a lab write up on your section only and this should include a purpose, materials/method, results and conclusion section. The questions listed in your section should be answered as well as the 2 common questions at the bottom of the chart. (As the research references are worth 5 marks, I expect at least 3 references to be used with journal articles being weighted more than references to the text book.)
Each one will do a 5-minute presentation on their section of the lab for the class briefly describing their results, and detailing the results of their research.
| Shielding | To observe the effects of shielding on patient dose |
| Position the pelvis and thorax phantom supine on the table. Using proper collimation, positioning and technique for an AP pelvis, you will take 6 exposures with the dosimeter in the indicated following positions: Female gonads (no lead) 59.25mRFemale gonads (lead). 567.3 μrMale gonads (no lead) 4.835mRMale gonads (lead) 17.48 μrSternum (no lead) 126.7mRSternum (lead). 475.8 μr Questions: Based on your results, is lead shielding effective in reducing exposure to sensitive body tissue? Is the reduction in exposure by a significant amount?Is lead shielding practical in all situations?Compare your results with findings in the literature. Do all literature sources agree on the use of lead shielding? |
Questions:
- What are the factors in radiography that affect patient dose? List them in three categories: the ones we have the most control over, the ones we have some control over, and the ones we have no control over.
- What are your responsibilities as a radiographer in reducing patient dose?
