What is Digital Infrared Thermal Imaging (DITI)?
DITI is a non-invasive diagnostic technique that allows 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 colour on a monitor. This visual image graphically maps the body temperature and is referred to as a thermogram. The spectrum of colours 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 asymmetry’s can be easily identified.

DITI's major clinical value is in its high sensitivity to pathology in the vascular, muscular, neural and skeletal systems and as such can contribute to the pathogenesis and diagnosis made by the clinician.
Clinical uses for DITI include:
- To define the extent of a lesion of which a diagnosis
  has previously been made
- To localize an abnormal area not previously identified,
  so further diagnostic tests can be performed
- To detect early lesions before they are clinically evident
- To monitor the healing process before the patient is
  returned to work or training
DITI has been used extensively in human medicine in the USA, 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.
