Your Digital Infrared Thermal Imaging Assessment Thermographers.


Clinical DITI is a noninvasive imaging 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 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.


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 effectivness and economic viability. Current state of the art PC based Infrared technology designed specifically for clinical application has changed all this.


Clinical uses for DITI include;

1. To help define the extent of a lesion of which a diagnosis has previously been made.

2. To localise an abnormal area not previously identified, so further diagnostic tests can be performed;

3. To help recognize abnormal areas that have potential to be 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°C by DITI.

The neuro-thermography application of DITI measures the somatic component of the sympathetic nervous system by assessing dermal blood flow. The sympathetic nervous system is stimulated at the same anatomical location as its sensory counterpart and produces a ‘somato sympathetic response’. The somato sympathetic response appears on DITI as a localised area of altered temperature with specific features for each anatomical area of interest.

The mean temperature differential in peripheral nerve injury is 1.5°C. In sympathetic dysfunction’s (RSD /SMP / CRPS) temperature differentials ranging from 1° C to 10° C depending on severity are not uncommon.


Rheumatological processes generally appear as ‘hot’ areas with increased temperature patterns. The pathology is generally an inflammatory process, i.e. synovitis of joints and tendon sheaths, epicondylitis, capsular and muscle injuries, etc. Both hot and cold responses may coexist if the pain associated with an inflammatory focus excites an increase in sympathetic activity.

What is Digital Infrared Thermal Imaging, or Thermography?

Digital Infrared Thermal Imaging (DITI), or Thermography, is the detection and study of heat patterns of the body. They help indicate normal or abnormal activity in the underlying tissue.

Why Use Digital Infrared Thermal Imaging?

Used adjunctivly, Thermography has the potential to improve the effectiveness of your current screening methods.  No contact, therefore 100% painless. No radiation, therefore 100% safe.

Thermography has been approved for this purpose by the FDA in the United States since 1982.

Thermography has the potential to be a Biological Risk Indicator.

Thermography of the Breast is a physiological test that assesses signs of disease development at the cellular stage, supporting early awareness through comparative studies.

Thermal imaging of the breast (or any other part of the body), is completely noninvasive, making it safe  for all women, especially those requiring more frequent monitoring, or who cannot tolerate radiation exposure and/or are challenged by the extremely high levels of DNA damaging Alpha Particle radiation and the issues associated with compression of sensitive breast tissue.

Thermography also examines generous areas of breast tissue in the upper chest and underarm areas.

How does thermal imaging work?

The camera of choice by Sunstate Thermal Imaging is specifically designed for thermal imaging of the human body in the clinic situation. The camera captures a thermal picture of body heat and displays the thermal patterns on a computer screen in the form of a digital image for analysis.

What happens is the cells of your body produce heat through their normal day to day activity.  Abnormal and diseased cells usually produce much more heat through a raised metabolism in their early  development and that is long before there is an anatomical marker or change in the structure.

Before the onset of most abnormal growth, suspect cells will stimulate new blood vessels to grow, reopen unused blood vessels and maintain those blood vessels already in use.

Some of these diseases build extensive network of blood vessels in the area in which it will begin to grow. Some diseases need more blood flow than normal cells to support their rapid growth.  Very simply, where there is more blood, there is more heat.  Thermal Imaging examiners take particular note of these  “hot spots” which can often be the earliest warning signs of abnormal activity. This activity has been shown to begin many years before anatomical change, and before  palpable signs.
