class  Gamma_dose_comparison 
The Gamma_dose_comparison class executes a comparison between two dose distributions based on the "gamma index" defined by Dan Low et al. in the following reference: Low et al, A technique for the quantitative evaluation of dose distributions, Med Phys. 1998 May;25(5):65661. The comparison is based on searching a local neighborhood for the most similar dose. The similarity is computed as the geometric mean of the dose difference and spatial distance. The gamma value at a point is then the minimum of this similarity value over the the neighborhood. Generally, the gamma value is normalized based on a spatial tolerance and a dose difference tolerance such that gamma values of less than 1.0 are acceptable, and gamma values greater than 1.0 are unacceptable.
