本发明所述的红外线热扫描系统， 其工作原理： 支气管组织内血管的血流， 动脉血温 度较高，静脉血温度较低，两者存在某种热交换机制，两者都向外辐射不同波长的红外线， 其温度不但受到血管内血流的影响，也受自身的新陈代谢的影响，所以支气管及其组织内 发生异变的部分的温度会由于血管丰富与否和新陈代谢的活跃程度的不同而表现出差异 性， 对外辐射的红外线的波长也各不相同。 研究表明， 血液中的成分（血清、 血浆、 血红 蛋白、 白蛋白、 红细胞、 淋巴细胞、 血小板）在光谱中对红外光的吸收最低， 意味着血液 除了对外辐射红外线外，还对周围组织的红外线的吸收影响很小，红外线热扫描系统的精 度小于等于 0.05度， 空间分辨能力至少达到 0.8mrad， 红外线热扫描探头在支气管内作近 距离进行扫描， 得到精细精确的红外图像。
本发明所述的红外线热扫描系统，其工作过程：支气管内血管中血流及组织辐射的红 外线， 通过进入支气管内的红外扫描探头的精密红外探测器-红外接收镜头接收后， 处理 芯片将光信号转换成电信号， 经过预处理 (如放大、 滤波等；)， 由前置放大器和主放大器放 大到一定电平之后便进入红外线热处理系统主机。同时输入主机的信号还有同步信号、参 照黑体信号等。多平面连续横切扫描得到的数据传输至红外线热扫描系统主机进行图像处 理， 输出到红外线系统监视器， 清晰显示支气管立体血管静态图像， 医生可通过图像进行 分析，可以发现支气管及周边组织血管异常丰富、血管异常稀疏或者存在血管缺失区域等 异常情况， 给医生及时提供即时的诊断依据。
本发明所述的红外线热处理系统主机，其后面板的输出端口外接操作键盘或手持操作 设备、红外线热扫描系统监视器等，红外线热扫描系统监视器的扫描与红外线热扫描探头 扫描相一致， 实现同步扫描。
本发明所述的具有红外线热扫描功能的电子支气管镜系统， 其临床手术方法如下所 述：患者首先做适当体位，做好消毒等准备工作，然后向患者喉部缓慢插入电子支气管镜， 缓慢在电子支气管镜提供图像下经过气管，进入支气管中进行观察，到达目标位置固定后， 从电子支气管镜的器械通道通入红外线热扫描探头的工作端部，红外线热扫描探头的工作 端部伸出电子支气管镜的先端部若干距离后，启动红外线热扫描功能，边退出电子支气管 镜， 边对支气管及周围组织进行扫描， 输出到监视器， 提供医生对支气管道潜在病症诊断 的依据。
与现有技术相比， 本发明的有益效果是：
目前的医用红外成像技术的红外分辨率的精度高， 而且已经逐渐广泛应用在很多领 域， 特别是医疗领域。本发明所述的具有红外线热扫描探头的电子支气管镜， 是以电子支
气管镜为平台， 引入红外线热扫描探头进入支气管内，利用红外线热扫描探头做线性和环 形的移动，对支气管壁血管血液运动产生的温度差异而形成的红外线辐射进行线性和环形 的扫描监测， 以得到多平面连续横切扫描成像,然后将多平面连续横切扫描得到的数据传 输至红外线热扫描系统主机进行图像处理，清晰显示支气管立体血管静态图像，为医生判 断支气管病变及功能状态提供可靠的客观依据。此外，本发明红外线热扫描处理系统提供 多种工作模式，包括普通显示模式和夜视显示模式， 医生可以通过分析和比较不同显示模 式的诊断图像， 做出正确诊断。本发明极大地丰富呼吸道疾病的诊断手段， 有效地提高诊 断的准确性。 附图说明
