近红外脉冲光乳腺疾病诊断系统功率谱和互相关曲线分析
Analysis on power spectrum and correlation curve of breast disease diagnosis system based on near-infrared pulsed light
摘要
Abstract
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.关键词
