11. A method comprising:
acquiring, by a computer system including one or more processors, a MR image of a subject with contrast illustrating one or more anatomical structures of interest;
applying, by the computer system, a global transformation to the MR image of the subject to generate a first morphed version of the MR image representing a first estimate of MR data of the subject in a template space;
applying, by the computer system, a local transformation to the first morphed version of the MR image of the subject to generate a second morphed version of the MR image representing a second estimate of the MR data of the subject in the template space;
projecting, by the computer system, boundaries of the one or more anatomical structures of interest from an anatomical template image onto the second morphed version of the MR image of the subject, the projected boundaries representing an estimate of the boundaries of the one or more anatomical structures of interest within the template space for the subject; and
applying, by the computer system, an inverse transformation to the estimate of the boundaries of the one or more anatomical structures of interest within the template space to determine a first estimate of corresponding boundaries of the one or more anatomical structures of interest in the MR image of the subject.
