摘要:

A software package has been developed to process perfusion, relaxation times and diffusion MRI dat a acquired in cancer research. This software package was written on MATLAB  platf orm (Version 6.0). Parameter maps, such as permeability, apparent diffusion coef ficient and T1 were generated from original MRI data. The features of para metric  analysis include ROI analysis, contrast adjust, statistical information generat ion, falsecolor image and zoomin display. Since it was written in Matlab fun ct ions, this package can be used on almost all operation systems (Microsoft window s, Unix, Mac OS & Linux) and it is easy to expand the features.

Abstract:

在MATLAB平台(6.0版本) 上编写了灌流、弛豫和扩散成像参数分析软件,来处理肿瘤研究中灌流和扩散成像的数据. 该软件能从原始数据得到灌流,扩散系数及T1弛豫时间等参数的分布图像,能进行局部区域数据分析. 该软件适用于Microsoft Windows 及UNIX计算机操作系统.
