a. Perform an extrinsic uniformity test using a medium or high sensitivity collimator with each of the following window widths: 5%, 10%, 15%, 20%, 25%, 30%, 40%, and 50%. Note the total counts and time for each image. Explain your protocol as perforemd in your department.
b. Graph sensitivity (counts/second/mCi) versus window width on linear graph paper. Submit your graph.
c. Discuss the effects of window width on sensitivity as evident on the graph.
d. Discuss the effects of window width on field uniformity as evident on the images.
e. Is there any situation in which a wide window width would be more appropriate than a narrow window width? Explain your answer.
f. Is there any situation in which a narrow window width would be more appropriate than a wide window width? Explain your answer.
g. Include 2 in-text citations and a reference page.

Use the given documents. Answer the questions and insert the given graph and images.
Sensitivity is inversely proportional to resolution (this is a useful note)
