摘　　要：乳腺癌是全球女性发病率和死亡率最高的癌症。采用红外热成像技术能发现早期乳腺癌,并降低死亡率。借鉴了国内外的相关研究成果,采用冷环境及热电激发双重诱导下的红外热成像方法来解决小尺寸癌变组织和乳腺深部癌变组织的红外热成像应用效果差的问题。红外热成像的对比度显著增加了,且通电模式下的温度对比度提高了26.5%。研究表明,热对比度主要受癌变组织大小、深度和温度的影响,同时还受环境温度和换热系数的影响。通过同时控制环境和热源温度的措施提高了热对比度,预期乳腺癌的早期筛查效果可提高50%以上。Breast cancer is the cancer with the highest morbidity and mortality among women worldwide.Using infrared thermal imaging can detect early breast cancer and reduce the death rate.The research results at home and abroad are used for reference,and the infrared thermal imaging method under the dual induction of cold environment and thermoelectric excitation is adopted to solve the problem of poor application effect of infrared thermal imaging of small size and deep breast cancerous tissue in the paper.The contrast of infrared thermal imaging is significantly increased,and the temperature contrast in the power-on mode is increased by 26.5%.The results show that the thermal contrast is mainly affected by the size,depth and temperature of the cancerous tissue,as well as the ambient temperature and heat transfer coefficient.In this paper,the thermal contrast ratio is improved by controlling the ambient and the heat source temperature at the same time,and the effect of early detection for breast cancer is expected to be increased by more than 50%.
