Thermography is a non-invasive imaging technique that uses infrared cameras to detect and visualize heat patterns in the body. It measures the temperature variations on the skin's surface, which can indicate underlying issues such as inflammation or poor circulation. This method is often used in medical diagnostics, as well as in fields like building inspections and electrical maintenance. The images produced by thermography, known as thermograms, can help healthcare professionals identify potential health problems without the need for radiation or physical contact. While it is not a standalone diagnostic tool, it can complement other medical evaluations and assist in monitoring certain conditions over time.
