DEVICE FOR ADAPTIVE PHOTOPLETHYSMOGRAPHY IMAGING |
摘要 |
The present invention proposes a device for detection of hemodynamic parameter maps in a human skin by means of remote photoplethysmography imaging with adaptive illumination. The device comprises a video registration unit adapted for registering set of video frames of region of interest of subject's skin, said region having a number of sub-regions; a data processing unit adapted for processing obtained video signals and extracting photoplethysmography signals and set of hemodynamic parameters from each of the sub- regions; a display unit adapted to display hemodynamic parameter maps; an illuminator adapted to provide uniform illumination of the region of interest; a driver for regulating a power of illuminator; wherein the device further comprises a feedback unit adapted to receive from the data processing unit, the PPG signals from each of the sub-regions and to provide control of the illuminator to maintain uniform illumination of the region of interest; triggering unit for synchronous triggering of illuminator and video registration unit. |
