Quantification of the local myocardial volume changes due to ethanol dehydration. (a) Colour maps of the local Jacobian determinants of the deformation field, J_D, at three levels from base to apex, obtained after the non-rigid registration between the heart before and 342 h after ethanol immersion. (b) Local J_D at three different image slices obtained after the non-rigid registration at full resolution within the ROI indicated with a dashed red rectangle. Reddish values indicated tissue expansion while blueish values indicated tissue shrinkage.
