  • Apparatus for detecting temperature variations over selected regions of living tissue, and method thereof
    Patent number: RE30446
    Abstract: An apparatus for detecting temperature variations over selected regions of living tissue. The invention relates to the apparatus and to the method of detecting said temperature variations for aid in the early detection of malignant tissue in the breasts. The invention provides for the use of liquid crystals encapsulated between elastic flexible sheets which represent a composite film. The crystals are responsive to changes in temperature of said tissue to display a color pattern on said film representative of said temperature variations. The film conforms to the contour of the tissue to which it is applied, without materially deforming said tissue, by evacuating air from between said film and said tissue. The color pattern produced on said film is observed and is recorded photographically to obtain a thermogram of said temperature variations.
