Color-coded strain fields in short axis mid-slice cross-sections, time frames 1,6, 11,16,21 (a full heart cycle subtends 42 frames), regularized through Gaussian convolution with spatial scale σ = 1.0, for one healthy volunteer. First row: Circumferential strain E cc. Second row: Radial strain E rr. Third row: Shear strain E cr. Fourth row: Minimal strain eigenvalue E min . Fifth row: Maximal strain eigenvalue E max .
