The liquid crystals utilized for thermography (LCT) are cholesterol derivatives which selectively reflect polarized light in a narrow region of wave lengths. They have strong molecular rotatory power and their molecular arrangement is altered by temperature changes. The latter property results in specific color-temperature responses which are utilized in color thermography.1,2 In the past, the adaptation of liquid crystals to thermography had been hampered by the necessity of skin preparation with black, water-based paint in the form of a spray, prior to the actual application of liquid crystals to the skin.1,3 Rigid plastic plates subsequently replaced skin preparation and spraying, but the unyielding plates precluded uniform liquid crystal-skin contact, particularly when applied to the spine or extremities. The resultant thermograms were, therefore, inadequate.
