摘要:

目的 提出一種乳腺疾病無損檢測(cè)新技術(shù)及其分析方法。方法 基于近紅外脈沖光的乳腺疾病診斷系統(tǒng)軟件部分以VC為開發(fā)工具,主要實(shí)現(xiàn)圖像同步采集、圖像配準(zhǔn)、分析處理和數(shù)據(jù)管理等功能,其中分析處理部分包含感興趣點(diǎn)分析和區(qū)域分析兩種方法,點(diǎn)分析主要包含功率譜曲線、相關(guān)性曲線和相關(guān)系數(shù),區(qū)域分析則是計(jì)算區(qū)域內(nèi)所有點(diǎn)相關(guān)系數(shù)形成由相關(guān)系數(shù)構(gòu)成的偽彩圖像。文中對(duì)一例典型的乳腺癌患者做了詳細(xì)的診斷分析。結(jié)果 乳腺癌患者病變部位的相關(guān)系數(shù)一般小于0.6,其功率譜呈現(xiàn)很多次頻峰,互相關(guān)曲線上出現(xiàn)很多毛刺。而正常人的相關(guān)系數(shù)基本都在0.8以上,其功率譜和互相關(guān)曲線較光滑。結(jié)論 該系統(tǒng)具備非侵入、無輻射、廉價(jià)的特性,通過對(duì)典型病例的光強(qiáng)分析展示了系統(tǒng)的臨床使用價(jià)值。

Objective To propose a new non-invasive detection technology for breast disease and the analysis method. Methods The software of the galactophore disease diagnosis system based on near-infrared pulsed light is developed with Visual C on the platform of windows. The software function is synchronized image acquisition,image registration,analysis of light signal and management of data in this system. The analysis function contains analysis of the interest points and the interest regions. Point analysis consists of the power spectrum curve,correlation curve and correlation coefficient. Region analysis utilizes the correlation coefficient of all points in the interest region to form a pseudo-color image for diagnosis. And a typical breast cancer case is diagnosed and analyzed by this system. Results Commonly,the correlative coefficient of focus in this case is under 0.6,and many wave crests appear in the power spectrum with many burrs in the correlation curve. However,the correlation coefficient of a healthy person is above 0.8,and the power spectrum and correlation curve is smooth. Conclusions This system is non-invasive,nonradiative and cheap. The analysis on the typical breast cancer case indicates the clinical application values.
