光源探测器阵列密度对近红外漫射光相关断层成像的影响
Influence of Source and Detector Array Density in Near-Infrared Diffuse Correlation Tomography
摘要
Abstract
Near-infrared diffuse correlation tomography(DCT)is a new technique for breast microvascular blood flow imaging,while the spatial resolution of imaging is insufficient.It is unclear whether the high-density source-detector(S-D)arrays can effectively improve the spatial resolution of DCT.In order to investigate the influence of S-D array density in DCT,three S-D arrays with S-D pairs of densities of 24,48 and 96,respectively,have been designed.Through a simulation study,which combined Monte Carlo simulation and DCT blood flow image reconstruction methods,we study the effect of S-D arrays on blood flow reconstruction in breast tissue containing two types of heterogeneity(simulating breast malignancy)with high blood flow.The results show that high-density S-D arrays with overlapped arrangements can improve the spatial resolution of DCT blood flow reconstruction.Application of this study to clinical breast tumor early screening may improve the accuracy and stability of DCT for breast malignancy.关键词
