化学交换饱和转移的Z谱分析展示系统
The system applying and analyzing of Z spectrum in chemical exchange saturation transfer
摘要
Abstract
Objective:To create a simple and friendly software toolkit to display and analyze Z spectrum of Chemical Exchange Saturation Transfer (CEST), which is convenient for clinicians and researchers to apply and research. Materials and Methods: The data is collected by conventional CEST imaging method, and the system is made by MATLAB GUI. Fitting the Z spectrum of different region of interest (ROI) which are selected by taking the mouse, and also carrying on its analysis and comparison. Results:The different positions and different pixel values of image’s ROI, the Z spectrum are different, which reflect different biological information. Conclusion:Z spectrum directly determines the final CEST signal analysis and relates biomedical information extraction. The functions of this system mainly include CEST image denoising, the formation of asymmetric magnetization transfer rate (MTRasym) mapping, selecting ROI and fitting the Z spectrum. To fit the Z spectra of ROI which are selected by taking the mouse.关键词
