ABSTRACT
The article focuses on experimental observations of coronary blood flow using the thermographic camera. The word thermography denotes pictorial recording of temperature. It should not be confused with direct infrared photography taken with an ordinary camera equipped with special film and filter. The thermographic camera measures and displays electromagnetic infrared radiation which is generated by the motion of charged atomic particles of any body with a temperature exceeding absolute zero. These waves behave as a stream of particles or photons composing a monochromatic beam of radiation.
