Figure 4-29. Base section measures only two inches.
c. Set mA the same as on the reproducibility test.
Make sure that the largest sensing field is used, and the density control is on
d. Select 60 kVp.
e. Place the cassette in the Bucky tray.
f. Place the lead numbers and identify the kVp and different thickness of the
phantom on top of phantom.
g. Record the data on the appropriate section of the form.
h. Make the exposure.
i. Record the exposure indicated on the digital timer display.
j. Repeat steps d through i for phantom thicknesses of four, six, eight, and ten
inches, using kVps of 80, 100, and 120 (see figure 4-30).
k. Process all films.
