FFD)
AP/PA Filter (57-405)
Build-Up Filter (Thin) (57-430)
Breast Shields (57-409)
Adult Gonad Shield (57-408) or Pediatric Gonad Shield (57-444)
For above average patients, position the AP/PA (57-405) filter 1" above the level of the external auditory
meatus. Place the Breast Shields (57-409) on top of the AP/PA wedge (57-405). Place the Thin Build-Up
Filter (57-430) on top of the Breast Shields, with the top edge of the filter at the mid-portion of the chin
(midway between the inferior alveolar border and the mental protuberance) (See Figure 5-3). The
purpose of the Build-Up Filter is to increase the attenuation of the x-ray beam in the cervical area. This is
necessary because exposure factors will have to be adjusted to properly expose the lumbar area, due to
increased abdominal density. The measurement is taken in the AP position at the level of the third lumbar
vertebra
When using the Build-Up Filters, always position
the steel slide against the magnet. Magnet against
magnet will result in filter movement due to
repelling magnetic fields.
