Medical imaging technique using infrared radiation
Thermography, also known as thermal imaging, is a non-invasive diagnostic technique that uses infrared radiation to detect and record temperature variations on the surface of the skin. This method is used in various fields, including medicine, veterinary medicine, and engineering.
Principles of Thermography[edit]
Thermography operates on the principle that all objects emit infrared radiation as a function of their temperature. The amount of radiation emitted increases with temperature, allowing thermographic cameras to detect and visualize temperature differences. These cameras convert infrared radiation into electrical signals, which are then processed to produce a thermal image or thermogram.
Medical Applications[edit]
In the medical field, thermography is primarily used as a diagnostic tool to detect abnormalities in body temperature that may indicate underlying health issues. It is particularly useful in the following areas:
Breast Thermography[edit]
Breast thermography is used as an adjunctive tool in the early detection of breast cancer. It can identify areas of increased heat, which may correspond to increased blood flow and metabolic activity associated with tumor growth. However, it is not a replacement for traditional imaging techniques such as mammography.
Musculoskeletal Disorders[edit]
Thermography can help diagnose musculoskeletal disorders by identifying areas of inflammation or injury. It is often used to assess conditions such as arthritis, tendonitis, and sports injuries.
Vascular Disorders[edit]
Thermography is useful in detecting vascular disorders by visualizing changes in blood flow. It can help identify conditions such as deep vein thrombosis and peripheral artery disease.
Neurological Disorders[edit]
In neurology, thermography can assist in diagnosing conditions like complex regional pain syndrome (CRPS) by detecting temperature asymmetries between limbs.
Advantages and Limitations[edit]
Thermography offers several advantages, including being non-invasive, painless, and radiation-free. It provides real-time imaging and can be used for continuous monitoring. However, it also has limitations. It is less specific than other imaging modalities and can be affected by external factors such as ambient temperature and skin conditions. Therefore, it is often used in conjunction with other diagnostic tools.
Thermography in Veterinary Medicine[edit]
In veterinary medicine, thermography is used to assess the health of animals by detecting temperature changes that may indicate injury or disease. It is commonly used in equine medicine to evaluate lameness and detect inflammation in horses.
Industrial and Engineering Applications[edit]
Beyond medicine, thermography is widely used in industrial and engineering applications. It is employed in building inspections to detect heat leaks, in electrical engineering to identify overheating components, and in mechanical engineering to monitor machinery for signs of wear or failure.
