Abstract

   The heat is one of the most important parameters of living beings. The tissues heat, generated at normal or diseases states, is lost to environment through several mechanisms: radiation, conduction, convection, evaporation, etc. Skin temperature is not the same on the entire body and a thermal body signature can be got. The temperature of neoplasic tissue is different up to 1.5 0C than the healthy tissue as a result of the specific metabolic rate. The infrared camera images show the heat transferred by radiation very quickly. A lot of factors disturb the conversion temperature-pixel intensity. A very sensitive sensor, a video camera showing its spatial position and a special computer fusion program were used for early cancer diagnosis. By using the high resolution maps, the diagnosis for about 78.4% of patients with thyroid cancer, and more than 89.6% from patients with breast cancer were right.
