[A rapid method of energy metabolism assessment in the human body using thermovision technology].

Quick method of energy metabolism assessment by direct calorimetry using thermovision technology for momentary registration of thermoreturn from whole human body surface is suggested. For realization this method an algorithm of computer program was developed for processing hundred thousands of points of skin temperature measures and temperature of surrounding environment. This method can be used for assessment of big groups of population.
