Thermography

Digital Infrared Thermal Imaging 

Medical DITI is a noninvasive diagnostic technique that allows the examiner to visualise 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 visualised in colour on a monitor.

This visual image graphically maps the body temperature and is referred to as a thermogram. The spectrum of colours indicate 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 asymetry's can be easily identified.

Medical DITI's major clinical value is in its high sensitivity to pathology in the vascular, muscular, neural and skeletal systems, and can contribute to the cinicians's pathogenesis and diagnosis. Medical DITI has been used extensively in human medicine in the U.S.A., Europe and Asia for the past 20 years. Until now, cumbersome equipment has hampered its diagnostic and economic viability. Current state of the art PC based Infrared technology designed specifically for clinical application has changed all this.

Clinical Uses

Clinical uses for DITI include:

1. To define the extent of a lesion of which a diagnosis has previously been made
2. To localize an abnormal area not previously identified, so further diagnostic tests can be performed
3. To detect early lesions before they are clinically evident
4. To monitor the healing process before the patient is returned to work or training

Skin blood flow is under the control of the sympathetic nervous system. In normal people there is a symmetrical dermal pattern which is consistent and reproducible for any individual. This is recorded in precise detail with a temperature sensitivity of 0.1℃ by DITI.
