Wavelength-dependent sensitivity of MRI-compatible camera and amplitude of PPG signal. Relative amplitude of a PPG signal obtained in reflectance PO from one volunteer and spectral sensitivity of the camera used in this study. Please note that the values of both curves were read by eyeballing diagrams found in the data-sheet of the camera and in literature [36]
