Analysis of different image-registration algorithms for Fourier decomposition MRI in functional lung imaging.

Background: Motion correction is mandatory for the functional Fourier decomposition magnetic resonance imaging (FD-MRI) of the lungs. Therefore, it is important to evaluate the quality of various image-registration algorithms for pulmonary FD-MRI and to determine their impact on FD-MRI outcome.

Purpose: To evaluate different image-registration algorithms for FD-MRI in functional lung imaging.
