Abstract/OtherAbstract:
|
Laser Doppler (LD) perfusion signals consist of a number of superimposed frequencies that span a wide range. Singular Spectrum Analysis (SSA) was used to characterise the Very Low Frequency (VLF) components as this method can extract frequencies of interest from the time domain. Its utility is demonstrated on a sex health clinical data set where the focus was on VLF oscillations. A significant change in this frequency range can be measured with SSA when the subject is undergoing erotic stimulation. |
