It’s all about the skin and a special infrared camera. Thermography can be used as a whole body analysis for assessing surface heat temperatures that can be correlated to health or abnormalities. Corresponding research over 30+ years has created standards of measurement. Uses for thermography are similar to that of an oral thermometer, a stethoscope, or any other medical tool that brings together a better physiological assessment of a patient.
The human body emits infrared radiation that a sensor on the thermal camera reads and translates into a temperature map. In certain areas a temperature variances of even 1 degree can indicate an abnormality in the body. A specialized high tech infrared thermal camera, a trained certified thermographer and an experienced interpreter (like a radiologist reading an x-ray) are the most important aspects to medical thermography.
