DtiStudio: Resource Software for Diffusion Tensor Imaging

本提案的目标是改进和维护我们的软件DtiStudio。主要有三 在这个软件中的功能。首先，它读取和处理扩散张量成像（DTI）的数据， 磁共振成像（MRI）技术。与其他MRI技术不同， 只有经过复杂的计算才能从DTI中获得，并且DTI数据处理工具不 随时可用。第二，软件提供了数据分析和量化的接口。不像 常规MRI，DTI每个像素包含6个参数。常规MRI分析软件， 因此，并不总是适用于DTI数据。第三，它允许白色物质的3D束重建 小册子。这也不是普通用户可以容易开发的技术。另一方面，在一项研究中， DTI正在成为各种脑部研究的重要工具。数据采集方案为 现在可在商业MRI扫描仪和DTI数据可以很容易地获得作为常规临床 实践对DTI数据处理和分析软件的需求正在迅速增长。我们现在的DtiStudio 拥有约3，000名注册用户，并且这个数字还在以平均40名用户的速度增长。 月软件维护和用户支持的工作量正在稳步增长， 同时软件的新功能也在迅速发展。根据这些情况，我们 要求设立一个基金，以实现以下四个目标; 目标1：建立在线手册系统。 目标2：多平台支持：当前的DtlStudio仅支持Windows平台。我们将港口 DtlStudlo到Linux、Unix和Mac OSX平台。 目标3：引入先进的软件管理和开源：DtiStudio的功能 这使得引入先进的软件管理系统变得非常重要， 为多个开发人员提供版本跟踪和工作环境。这也提供了一个环境， 开源. 目标4：升级以整合新技术。

The goal of this proposal is to improve and maintain our software DtiStudio. There are three main functions in this software. First, It reads and process data for diffusion tensor Imaging (DTI), a modern technology of magnetic resonance imaging (MRI). Unlike other MRI techniques, various types of images from DTI can be obtained only after complicated calculations and DTI data processing tools are not readily available. Second, the software provides interface for data analysis and quantification. Unlike conventional MRI, DTI contains 6 parameters in each pixel. Conventional MRI analysis software, therefore, is not always applicable for DTI data. Third, it allows 3D tract reconstruction of white matter tracts. This is again not a technique that can be readily developed by average users. On the other hand, DTI is becoming an important tool for various types of brain researches. The data acquisition scheme is now available in commercial MRI scanners and DTI data can be obtained easily as routine clinical practices. Needs for DTI data processing and analysis software is rapidly growing. Our DtiStudio now has approximately 3,000 registered users and the number is growing with an average rate of 40 users I month. The work load for software maintenance and user support is steadfastly growing while simultaneously new functions of the software are rapidly evolving. Based on these circumstances, we are asking for a fund to pursue following 4 aims; Aim 1: Establish a system for online manuals. Aim 2: Multi-platform support: The current DtlStudio supports only Windows platform. We will port DtlStudlo to Linux, Unix, and Mac OSX platform. Aim 3: Introduction of advanced software management and open source: The functionality of DtiStudio is ever growing, which makes it important to introduce advanced software management system for version tracking and working environment for multiple developers. This also provides an environment for open source. Aim 4: Upgrade to integrate new technologies.
