摘要
阐述了一套基于频域技术的新型近红外光学乳腺成像系统.与本实验室曾经研制过的多光源、多探测器样机相比,此系统采用单光源、单探测器,因而从根本上避免了多通道成像系统中各路之间不匹配的现象,并简化了结构,同时降低了成本.仿体实验和临床实验结果证明,本系统具有较高的灵敏度和分辨率,可能成为一种行之有效的乳腺癌检测方法.
A newly developed near-infrared optical mammographer based on frequency-domain techniques was presented. In comparison with our former prototype with multiple sources and detectors, the new one used single source and detector. This structure not only eliminates the matching issues between the channels but also simplifies the system and reduces the cost. The results of intralipid and clinical experiments have proved that the system has high sensitivity and resolution, which indicates its promising potential to serve as a proficient method of breast cancer detection.
