Thermography is using thermal infrared imaging to detect health concerns like breast cancer. Here’s the
background on how this works.
In 400 BC the Greek physician Hippocrates wrote “In whatever part of the body excess of heat or cold is felt, the disease is there to be discovered.”
Temperature has long been established as a health indicator. It’s why when you see a doctor the nurse will do three things:
-
take your blood pressure,
-
take your heart rate,
-
and take your temperature.
If your temperature is elevated, then there’s a health concern that something is going on in your body that needs to be addressed. But for some reason that same application is not applied to looking at a thermal scan of your body, which is what thermography does.
