1. A method for obtaining strain corresponding to an object'"'"'s deformation by tagged magnetic resonance imaging (MRI) in a radial direction in which a substantially normal strain element is found in a direction substantially perpendicular to the radial direction for tagging, comprising acts of:

  • acquiring data of at least one crown region in a spatial frequency domain of an object at a primary state and at least one deformed secondary state;

    reconstructing one primary-state image of the primary state and one secondary-state image for each deformed secondary state, where the primary-state image and each secondary-state image are filtered and regionally weighted by a radial tag line density of the object; and

    determining the strain in the object in the direction substantially perpendicular to the radial direction for tagging by comparing the primary-state image with secondary-state image.
