Digital Infrared Thermal Imaging (DITI) is unique in its capability to show physiological change and metabolic processes. X-ray, C.T. Ultrasound and M.R.I. etc., are tests of anatomy. E.M.G. is a test of motor physiology. DITI has proven to be a very useful complementary procedure to these and other diagnostic modalities. Unlike most diagnostic modalities it is non-invasive. It is a very sensitive and reliable means of graphically mapping and displaying skin surface temperature. With DITI you can diagnose, evaluate, monitor and document a large number of injuries and conditions, including soft tissue injuries and sensory/autonomic nerve fiber dysfunction.
