Key result
Spline surface interpolation accurately reconstructed 3-D displacements of MRI tag lines with 2.4% error, but the strain solution magnified small errors in locating tag lines.
A novel spline surface interpolation method accurately reconstructs 3-D displacements from MRI tag lines, though strain calculations magnify small detection errors.

Strain metrics from MRI tags warrant caution pending validation; extends spline methods for displacement but leaves clinical adoption open.
Moulton et al. (1996) studied Ventricular strains. Spline surface interpolation vs. Finite element elasticity solution was evaluated on 3-D displacement reconstruction errors and strain fitting errors. Spline surface interpolation accurately reconstructed 3-D displacements of MRI tag lines with 2.4% error, but the strain solution magnified small errors in locating tag lines.
