Abstract:
In this paper, a new medical imaging strategy based on mobile phone is developed to obtain the quantitative temperature mappings of human skin. The visual images reflected by the TLC pre-painted on human skin are captured by the camera of mobile phone and transformed to the thermographies of human skin through digital image processing method according to the Temperature-Hue curve pre-established in the calibration experiment. The mobile phone acquired imaging is then applied to reconstruct the temperature distribution of dorsal hand and for thermodynamic check. Additional thermal parameters related to body health status are calculated based on the bioheat transfer model of human body. The present method is expected to be developed as a pervasive and low cost way to map the skin temperature imaging of human body.
