Back injury. Liquid crystal thermogram of the torso of a male patient suffering back injury. The distribution of colours and their symmetrical patterns is the thermographic method used here to diagnose the injury. The affected area is first painted black,then a clear liquid (cholesteric) crystal solution is sprayed over. The crystals are affected by temperature variations of skin and tissue and change colour. Blue/green shows good blood flow; red/black shows cooler areas. The red/ black area shows assymetric patterning occurring in the lower back,to reveal lower back injury. The affected area is cooler.
