a. Remove artifacts.

Arms at side, no rotation of shoulders or pelvis, looking straight ahead
With both shoulders against cassette, adjust height to place the center of the
unmasked half of the cassette to the level of the AC joints

h. SID: 72"
joints perpendicular to film
with a long narrow light field
to area of interest (7 x 17")
