f. Lock the fluoroscopic assembly in place both transversely and longitudinally.
g. Lower the fluoroscope assembly to just touch the test pattern.
h. Put on your lead apron.
i. Select 60 kVp fluoroscopic technique for this test.
j. Begin the fluoroscopic exposure.
k. Observe the image of the resolution test pattern.
l. Note the number of the wire mesh that you can clearly see in the viewed
m. Record the number value on the data form under the correct mode and image
intensifier field size.
n. If your unit has a magnification mode, repeat the above process.
o. Record the number value in the appropriate section of the data form.
If the system is equipped with cine film or photospot capability, make a test
film run of recording mode in each intensifier mode. Use 60 kVp and the
small focal spot.
p. Process and identify the test films from each film recording system tested.
5-16. EVALUATION AND INTERPRETATION
It may be necessary with small format film to examine the test films with a
magnifying glass or appropriate projection system.
a. Determine the smallest mesh resolved in the system.
b. Record the results on the data form.
c. Compare the test results with the minimum resolvable mesh chart or the
established clinic standards.
d. Make a note of any difference between the results and the established
