Cadmium K-edge Mammo Filter Pack Option (37355)
4.1 Introduction
The Cadmium K-edge Mammo Filter Pack (37355) provides a non-invasive way to make kVp
measurements of mammographic X-ray generators. This filter pack uses the inherent stability of the
Cadmium K-edge as an absolute reference for precision measurements between 27.5 and 29.5 kVp (for
beryllium window, molybdenum anode mammographic generators with molybdenum filtration). When
used in conjunction with the Linear Mammo Filter Pack (37351), precision calibrations of ± 1.0 kV
accuracy can be performed from 22 to 40 kV.
