中文摘要	通过构建人体三维生物传热模型,对含肿瘤组织的体表热图表现进行评估,发现当前远红外成像设备在诊断早期或深层肿瘤时,由于精度和分辨率所限,不易得到准确的诊断结果。在此基础上,设计不同制冷水平下的概念性红外成像实验予以证实,并对应提出一种超低温双腔体冷却方法,以期改善现有红外设备冷却方式,从而提高其成像精度和准确度。本文研究对于肿瘤早期影像学诊断具有现实意义。; 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.; 国家自然科学基金(50776097)资助
