Thermography is DITI used to detect and monitor a number of diseases and physical injuries. Thermal patterns indicate areas of reduced or increased activity, signifying changes of inflammatory activity or abnormal blood flow which can indicate disease or dysfunction. By visualizing thermal abnormalities present in the body, such as lymphatic congestion, pain, metabolic processes, and physiological (or functional) changes over time, thermography can help detect these abnormalities at their earliest stages.
