A Correction Method of Medical Thermography's Distortion.
A problem of temperature distortion of medical thermography of the limb ending which results from different infrared radiant intensity of points detected by infrared detector was discussed. Further the difference of the radiant intensity is caused by that of projecting angles of points. Subsequently through related theory and experiments this paper found that the temperature shown by thermography bears a Gauss attenuation relation to actual surface temperature of an object. A Gaussian Matching Arithmetic was put forward to correct this kind of temperature distion. Finally, by using this Arithmetic a temperature distortion of thermography of a finger was corrected and the results were exciting.
