Dynamic and Static mode in medical thermal image
In thermography, we have the choice to observe the moment, in static, the evolution or provoque ourselves the chance, that's the dynamic mode.
Dynamic mode request a broad experience in order to master the consequences of the stimulation and their limits. It requests too to catch the desired instant because dynamic is by definition fugace...
A lot of things can be observe, the change voluntary provoqued or the fall back to normality, evolution or new equiliar point.
Observation of the change itself
At left, original situation, static mode, inverted gray palette.
At right, dynamic observation after subject kept in her hands a gel coolpack at a temperature of around 10°C during 3 minutes.
Quality of image is completely changing and patterns are now well sharp. Of course first image allows already to analyze the situation but second is clearly easier to interprete and this finally remove minor points from the observation.
In some case, this is the only way to reveal an infection or illness who's quite discrete without this kind of protocol.
