Table 6 3D ANTs registration parameters
From: Optimisation of the air fraction correction for lung PET/CT: addressing resolution mismatch
Parameter | Setting |
|---|---|
Transformation model | Symmetric diffeomorphic (SyN) |
Transformation | fast symmetric normalisation: affine + deformable transformation, with mutual information as optimisation metric. Gradient-descent step-size: 3 |
Similarity metric | Fast cross-correlation (window radius:4; weight: 1) |
Optimisation | 4 level resolution pyramid (25, 50, 25, 5 iterations) |
Regularisation | 12\(\sigma\) FWHM Gaussian on the gradient; 3\(\sigma\) FWHM on the deformation field |
