Figure 29 - Positioner/Chamber relationship
Chamber Positioner
The chamber positioner locates an ion chamber at a fixed height from the x-ray table. Holes in the base
of the chamber positioner locate the kV sensor relative to the ion chamber to control the effect of
backscatter from the kV sensor on exposure measurements. Because mammography measurements
using th 6M chamber are less affected by backscatter, the mammography kV sensor may be positioned
closer to the chamber. The Figure 29 shows suggested arrangements.
