Web accessible aMR I/fMRI database

描述(由申请人提供)：我们建议开发一个适用于神经信息学工具验证研究的模拟AMRI(3D)和功能磁共振数据集(4D)的综合数据库。该项目将基于现有的磁共振成像模拟器MRISIM，该模拟器产生高真实感的磁共振成像数据，根据第一原理对磁共振成像信号的产生、数据采集过程和噪声传播进行建模。该项目的数据库方面将扩展现有的原型核磁共振图像数据库和开发的网络界面，以允许上传/下载核磁共振数据。拟议的项目有三个具体目标： 目的1：增强MRI模拟器，以适应AMRI和fMRI的应用。 目标2：创建用于工具验证的模拟/真实数据的AMRI/fMRI数据库。 目标3：为大规模AMRI/fMRI数据库增强现有数据库/文件格式资源。

DESCRIPTION (provided by applicant): We propose to develop a comprehensive database of simulated aMRI (3D) and fMRI datasets (4D) suitable for use in neuroinformatics tool validation studies. The project will be based upon an existing MRI simulator, MRISIM, which produces highly realistic MRI data, modeling the MRI signal generation, data acquisition process and noise propagation from first principles. The database aspects of the project will expand upon an existing prototype MRI image database and Web interface developed to allow uploading/downloading of MRI data. The proposed project has three specific aims: Aim 1: Enhance the MRI simulator for aMRI and fMRI applications. Aim 2: Create aMRI/fMRI databases of simulated/real data for tool validation. Aim 3: Enhance existing database/file format resources for a large-scale aMRI/fMRI database.
