这项工作提出了ISMRM原始数据（ISMRMRD）格式作为通用的MR原始数据格式，促进了算法和数据共享。设计了一种由灵活的标头和 k 空间数据标记帧组成的文件格式。应用程序编程接口是用 C/C++、MATLAB 和 Python 实现的。 Bruker、通用电气、飞利浦和西门子专有文件格式的转换器是用 C++ 实现的。使用来自四个供应商的 MRI 扫描仪收集原始数据，转换为 ISMRMRD 格式，并使用以三种编程语言（C++、MATLAB、Python）实现的软件进行重建。图像是通过重建所有供应商的原始数据获得的。这项工作的源代码、原始数据和图像在网上共享，作为遵循可重复研究范式的图像重建项目的示例。所提出的原始数据格式解决了 MRI 社区的实际问题。它可以作为可重复研究和合作的基础。 ISMRMRD 格式是一种完全开放且社区驱动的格式，邀请科学界（包括商业供应商）作为用户或开发人员参与。
This work proposes the ISMRM Raw Data (ISMRMRD) format as a common MR raw data format, which promotes algorithm and data sharing. A file format consisting of a flexible header and tagged frames of k-space data was designed. Application Programming Interfaces were implemented in C/C++, MATLAB, and Python. Converters for Bruker, General Electric, Philips, and Siemens proprietary file formats were implemented in C++. Raw data were collected using MRI scanners from four vendors, converted to ISMRMRD format, and reconstructed using software implemented in three programming languages (C++, MATLAB, Python). Images were obtained by reconstructing the raw data from all vendors. The source code, raw data, and images comprising this work are shared online, serving as an example of an image reconstruction project following a paradigm of reproducible research. The proposed raw data format solves a practical problem for the MRI community. It may serve as a foundation for reproducible research and collaborations. The ISMRMRD format is a completely open and community-driven format, and the scientific community is invited (including commercial vendors) to participate either as users or developers.
