The present work demonstrates that a low cost, flexible and user-friendly workstation for the MRI laboratory can be implemented by using a personal computer and public-domain software. The workstation is based on a Pentium personal computer, operating under the Linux operative system, and uses the software Khoros (Khoral Research, Albuquerque, NM). This software is a general purpose package for handling signals and we here report its suitability for MR images analysis. Khoros allows to create workspaces where different procedures (also written by the users) can be combined for implementing more complex procedures. We created workspaces for obtaining 2D and 3D images from time domain data which also allow for apodization and zero-filling. The time required for a 3D-FFT (matrix size 128x128x128) is about 12 min with the presently used microprocessor. We have also created workspaces for calculating apparent diffusion coefficient maps and for segmentation of MR images. Our results demonstrate that a personal computer equipped with public-domain software can represent a powerful tool to fulfil the MRI laboratory common needs.
目前的工作表明，通过使用个人计算机和公共领域软件，可以为MRI实验室实现一个低成本、灵活且用户友好的工作站。该工作站基于奔腾个人计算机，在Linux操作系统下运行，并使用Khoros软件（Khoral Research，阿尔伯克基，新墨西哥州）。此软件是一个用于处理信号的通用软件包，我们在此报告其适用于MR图像分析。Khoros允许创建工作区，在其中可以组合不同的程序（也可由用户编写）以实现更复杂的程序。我们创建了用于从时域数据获取2D和3D图像的工作区，这些工作区还允许进行加窗和零填充。使用当前的微处理器，3D-FFT（矩阵大小为128x128x128）所需的时间约为12分钟。我们还创建了用于计算表观扩散系数图和分割MR图像的工作区。我们的结果表明，配备公共领域软件的个人计算机可以成为满足MRI实验室常见需求的强大工具。
