摘要:

目的 基于光的组织传播特性和去氧血红蛋白和含氧血红蛋白对近红外光的相反吸收特性,本文设计和实现了一种近红外脉冲光乳腺疾病诊断系统。方法 系统由光源、控制电路、采集卡、近红外CCD相机和计算机及应用程序组成,光源选用波长为760nm和850nm,外部电路同采集卡配合实现光源的时序发光。结果 该系统具备非侵入、无辐射、廉价的特性。结论 作为一种辅助诊断技术,本系统有很重要的临床研究价值和应用价值。

Objective A breast disease diagnosis system based on the characteristics of near-infrared light is designed and implemented in this paper. Methods The system consists of light source,external control circuit of light source,capture card,near-infrared CCD camera,computer and the application software. The wavelength of 760nm and 850nm LED is selected as light source,external control circuit and capture card are used to implement sequential emitting of light source. Results The characteristic of this system is non-invasive,nonradiative and cheap. Conclusions This system is important in clinic research and application.
