1. A computer-implemented method for generating a respiratory signal from computer tomography (CT) scans, the method comprising:

  • retrieving, by one or more data processing apparatuses, a plurality of CT scans of an anatomical feature of a human from one or more computer-readable storage devices in which the plurality of CT scans are stored;

    determining, by the one or more data processing apparatuses, from the plurality of CT scans, a plurality of respiratory features;

    generating, by the one or more data processing apparatuses, a respiratory signal for each respiratory feature directly from the plurality of CT scans based on the plurality of respiratory features and an optimal respiratory feature selected from the plurality of respiratory features; and

    from the respiratory signals identified for the plurality of respiratory features, deriving a spatial coherence which is an average pair-wise correlation coefficient, wherein the correlation coefficient is a measure of a quality of the respiratory feature, wherein the spatial coherence is calculated as
