1. A method for selecting data to reconstruct a three-dimensional (3D) image of a subject of interest, said method comprising:

  • acquiring a 3D emission dataset of the subject of interest;

    acquiring a respiratory signal of the subject of interest, the respiratory signal including a plurality of respiratory cycles;

    calculating a respiratory profile using the respiratory signal;

    for each respiratory cycle, generating a gating window, calculating a minimum total squared difference (TSD) between a plurality of phases in the respiratory profile and the same plurality of phases in the respiratory cycle, and positioning the gating window based on the TSD values calculated; and

    reconstructing a 3D image using only the emission data within the plurality of gated windows.
