A Comparison of Hyperelastic Warping of PET Images with Tagged MRI for the Analysis of Cardiac Deformation
Table 1
Sensitivity results for Heart 1. The sensitivity study results for the Heart 1 analyses indicate that warping was relatively insensitive to image noise, moderate decreases in image intensity, and changes in fiber orientation. An SNR level of 1 (bold) caused severe degradation of the registration results with large increases in %RMSE and a reduction of the values. The lack of active contraction in the analysis also resulted in degradation of the error measures.
