Three-dimensional deformation analysis of human organs is very important from both diagnostic and therapeutic point of view. For example, comparing the deformation field in healthy and pathologic cardiac walls in the systolic phase allows to gather early and accurate information on the onset of heart diseases. MRI tagging is utilized in medicine to visualize with a great deal of detail the structure and morphology of tissues. The tagging process introduces a volumetric system of planes of reference similar to the process of introducing a grating in the 3-D moiré method in transparent media. The paper will analyze the kinematics of 3-D deformation fields and the fundamental concepts involved in 3-D deformation analysis within the restrictions imposed by the MRI method thus providing solutions for the inherent shortcomings encountered in the MRI tagging technique.
