近红外漫射光子乳腺癌检测成像系统

NIR Diffusive Optical Imager for Breast Canser Detection

结合近年来国际上利用近红外激光对生物组织内部成像的一些进展，研制了一台自动扫描的近红外漫射光乳腺癌检测和成像系统。该系统利用射频光子密度波来探测生物组织内部的异物，采用特殊的光源和接收器排列以应用简单的算法进行异物的3维定位。在此基础上，进行了大量的仿体实验以及一些人体实验，考察了系统探测和区分小异物的能力，揭示了好的临床应用的前景。

An automatic scanning near infrared diffusive optical imager for breast cancer detection was developed, which combined the international progress in tissue imaging with near infrared laser in recent years. This system employed diffuse photon density wave (DPDW) to detect the heterogeneities in biological tissues, and the rows of its laser sources and detectors were placed in a special way which made it possible to employ a simple algorithm for three-dimensional localization of heterogeneities. On the basis of this system, a lot of simulation experiments and a few human experiments have been conducted, which examined the abilities of this system in detecting and distinguishing small heterogeneities and enlightened the prospective future for the clinical application.
