Thermography is also known as Digital Infrared Thermal Imaging.
Clinical Thermography uses special equipment to measure the temperature of the skin’s surface. The skin responds with heat after receiving a message from the nervous system. What shows up on a scan is the nervous system’s reaction to pain, pathology, injury or dysfunction in the body. It’s like a reflex, when the doctor hits your knee with a hammer, you kick. Other diagnostic methods such as mammography, radiography or ultrasound may show the body’s structures while Thermography will show physiological and metabolic processes that are taking place.
For short, we will refer to Digital Infrared Thermal Imaging as DITI. Medical DITI enables the examiner to visualize and quantify changes in skin surface temperature. An infrared scanning device is used to convert infrared radiation emitted from the skin surface into electrical impulses that are visualized in color on a monitor. This visual image graphically maps the body temperature and is referred to as a thermogram. The spectrum of colors indicates an increase or decrease in the amount of infrared radiation being emitted from the body surface. Since there is a high degree of thermal symmetry in the normal body, subtle abnormal temperature asymmetries can be easily identified.
These thermal patterns displayed on the thermogram are as unique as fingerprints. In healthy people there is a symmetrical thermal pattern that is consistent and reproducible for that individual. Injury or disease will result in thermal asymmetries. DITI, using our state of the art, Flir digital thermal cameras will record these thermal patterns in a thermograph in precise detail with a temperature sensitivity of 0.01°C.
Medical DITI is a monitor of thermal abnormalities present in a number of diseases and physical injuries. It is used as an aid for diagnosis and prognosis, as well as therapy follow up and rehabilitation monitoring, within clinical fields that include Rheumatology, Neurology, Physiotherapy, Sports Medicine, Oncology, Pediatrics, Orthopedics and many others.
A specific interest exam takes about 20 minutes while a full body exam takes between 30 and 45 minutes.
Medical DITI is the only method available to visualize and assess pain and pathology anywhere in the body. Results obtained through thermography are totally objective and show excellent correlation with other diagnostic tests.
