Contactless system and method for assessing and/or determining hemodynamic parameters and/or vital signs |
| abstract |
A contactless system for assessing and/or determining hemodynamic parameters and/or vital signs is featured. The system includes one or more contactless light sources configured to emit light incident on a moving living subject at one more wavelengths absorbed by one or more chromophores associated with spontaneous hemodynamic oscillations in a predetermined area of the living subject. The system includes a camera subsystem including one or more cameras configured to receive reflected light from the predetermined area of the moving living subject and configured to track motion of the predetermined area of the living subject within a field of view of the camera subsystem and configured to generate a time sequence of images of the predetermined area of the living subject. A controller is coupled the one or more light sources and the camera subsystem and is configured to acquire the time sequence of images and configured to generate one or more non-contact PPG waveforms and to assess and/or and determine one or hemodynamic parameters and/or vital signs from the one or more non-contact PPG waveforms. One or more polarizers are preferably each coupled to one of the one or more light sources are preferably configured to polarize the light to a polarized state such that the polarized light in the polarized state diffuses into the tissue in the predetermined area at a predetermined depth range and the polarized light is maintained in the polarized state at the predetermined depth range. A detector polarizer is preferably coupled to each of the one or more cameras and is configured to discriminate the light maintained in the polarized state and at the predetermined depth range and configured to generate the time sequence of images of the predetermined area with improved signal quality of the resulting non-contact PPG waveform. |
