title: [Increase in the information content of thermograms by compensating for tissue heat conduction].
abstract: There exist two groups of factors responsible for distorsion of thermograms, these are a subdued temperature relief due to thermal conduction of tissues and equipment-caused distorsions. Such distorsions lower the informativeness of thermograms which hampers the selection of diagnostic signs. A method is proposed which enables it to partially compensate distorsions through application of Viener's method of re-establishing distorted images, based on the use of the à priori information on the distribution of temperature on the surface of the body and on the probable properties of thermal fields. The equipment-caused distorsions are then considered to be insignificant. The proposed algorythm of re-establishment has been tried out on the image of blood vessels in the rabbit's ear and on the factual image of the thermal field, the thermograms of mammary glands.
