Introduction to Medical Thermography or Thermal Imaging. |

Some Basics of Thermal Imaging Data is compiled by a computer into a thermal image and displayed on the instrument display screen. This is the recording of the skin's surface temperature by non-contact sampling and analysis of the infrared emissions from that surface. Thermal imaging is non-invasive as it is non-contact, and emits no ionising radiation, and therefore there is no pain involved in thermal imaging. A Thermal Imaging Scanner (or camera) measures infrared energy (heat) radiated from a body, accurately converting it to thousands of equivalent temperature readings. In the image known as a thermogram, Whites, reds and yellows typically represent the warmer end of the temperature range being displayed. Blacks, blues and greens generally represent the cooler end of the same range. A computer program assigns particular temperature ranges a particular colour, and then displays the now colourised temperature readings as a colour image which is a thermogram or thermograph. A sixteen colour palette including black and white covering an eight degree range has been established as a standard for all thermograms. This means that any one colour covers a band of temperature just half a degree centigrade wide. Cold Patterns (hypothermia) (Hypo -deficient, thermo -temperature) Cold patterns typically represent a decrease in blood supply. Nerve irritation or dysfunction and restricted circulation can produce thermographic cold patterns. Cold asymmetries (lack of symmetry) mostly result from (sympathetic) nerve irritation. Nerve irritation can trigger muscles around the blood vessels to contract, even virtually stopping the supply of blood to an effected area. Hot Patterns (hyperthermia) (Hyper -excessive, thermo -temperature) Heat patterns typically represent an increase in blood supply and local tissue temperature, which is the definition of inflammation. Wounds, blood pooling, complete nerve malfunction or abnormal blood vessel formations/alterations typically produce thermographic heat patterns. |
