开发了一个用于扩散张量图像(DTI)计算和纤维跟踪的通用资源程序。该软件可以从各种磁共振扫描仪读取数据格式。张量的计算是通过最小二乘拟合法求解一个超定的线性方程组来实现的。可以计算各种类型的地图数据，例如张量元素、特征值、特征向量、扩散各向异性、扩散常数和颜色编码方向。结果以交互方式在正交图和三维模式下可视化。三维重建是基于光纤分配的连续跟踪(FACT)算法和蛮力重建方法。为了提高时间和存储效率，采用了一种快速算法来执行FACT。引入了用于光纤数据的索引矩阵，以便于基于采用多个感兴趣区域(ROI)的方法来选择各种类型的光纤束。程序是在Windows平台上用C++和OpenGL开发的。(C)2005爱思唯尔爱尔兰有限公司。保留所有权利。
A versatile resource program was developed for diffusion tensor image (DTI) computation and fiber tracking. The software can read data formats from a variety of MR scanners. Tensor calculation is performed by solving an over-determined linear equation system using least square fitting. Various types of map data, such as tensor elements, eigenvalues, eigenvectors, diffusion anisotropy, diffusion constants, and color-coded orientations can be calculated. The results are visualized interactively in orthogonal views and in three-dimensional mode. Three-dimensional tract reconstruction is based on the Fiber Assignment by Continuous Tracking (FACT) algorithm and a brute-force reconstruction approach. To improve the time and memory efficiency, a rapid algorithm to perform the FACT is adopted. An index matrix for the fiber data is introduced to facilitate various types of fiber bundles selection based on approaches employing multiple regions of interest (ROIs). The program is developed using C++ and OpenGL on a Windows platform. (c) 2005 Elsevier Ireland Ltd. All rights reserved.
