title: [Deeply cooled far-infrared thermal imaging strategy for early tumor diagnostics].
abstract: This paper is dedicated to evaluate the thermal behavior of skin surface embedded with tumor tissue through construction of three-dimensional heat transfer model of the human body. It was found that the far-infrared imaging equipment could not yet get the accurate results for diagnosis of tumors developed in early stage or located deeply in the human body, because of limited resolution and accuracy in the current system. Conceptual experiments with a thermal imaging system under various cooling levels were performed to confirm this issue. A dual cooling cavity was proposed to realize ultra-low-temperature so as to improve the cooling of the current infrared equipment and thereby to enhance its image precision and accuracy. This study is expected to be of significant reference value for realizing an early diagnosis of cancers through medical image.
