When all elements of diagonal FLE and TLE covariance matrices are independently generated from a uniform distribution that spans from 0 to 1mm and the number of \ufb01ducials N\u22656, the mean and covariance matrix of TTRE are well modelled. We have also theoretically proved and validated through the second simulation that TTRE and \ufb01ducial registration error (FRE) are uncorrelated (correlation coef\ufb01cient (CC) &lt;0.1).
