In this paper, we propose a modified variational splines fitting (MVSF) algorithm for the reconstruction and comparison of medical surfaces. The MVSF algorithm presents the advantage to use high precise and low complex approximation of the equations of energy in the discrete temporal domain, compared to previously presented methods. It also takes into account the periodicity constraints encountered when reconstructing sphere-like shape closed surfaces. Moreover, it gives straightly the mean square error (MSE) between the original data and the reconstructed data, which is useful to quantify the approximation introduced by the reconstruction. The developed model has been successfully applied for real biomedical data; in particular for the reconstruction and comparison of the left ventricle of human heart, acquired by SPECT and ultrasound imaging modalities.
