Abstract
A PPG imaging system and method is provided for processing 3D images to derive remote PPG signals. A surface mesh of a region of interest is created from each of a set of the 3D images. The surface meshes are matched to each other using mesh transformations thereby providing motion compensation. A remote PPG signal is then obtained from each of a set of mesh locations of the matched surface meshes, thereby to derive a set of PPG signals. A perfusion map and/or a PPG delay map may be obtained from the set of PPG signals.
