1D Uniformity NCSΒΆ

This is the maximum variation in the ratio of the absorbed dose at any point in the flattened area to that of the central axis expressed as a percentage difference between the lowest and highest value of this ratio according to NCS 70 eq 3-5.

\[\cfrac {100} {cax} \cdot maximum \left[{|max - cax|}, {|min-cax|} \right ]\]

Where max, min and cax are the profile maximum, minimum and central axis values respectively.

Protocol invocation name: 1D Uniformity NCS

Note The max, min and cax are affected by normalisation or windowing.
