Self-calibrated B₁⁺ and B₀ Field Inhomogeneities Estimation (SAFE) in 3D Magnetic Resonance Fingerprinting

This dataset contains whole-brain 1mm isotropic quantitative MRI maps (T1, T2, PD), coil sensitivity maps, and paired 4mm isotropic field maps (B0, B1+) of 20 healthy adult volunteers. All data were acquired on 3T GE and Siemens scanners, with approval of the institutional review board, and informed consent was obtained. The tissue quantitative maps were acquired using 3D Spiral Projection Imaging MR Fingerprinting (MRF), while the field maps were acquired from calibration scans. Such a resource enables the community to utilize the SAFE method on their own specific MRF acquisition protocols without the need to obtain additional paired training data.本数据集涵盖20名健康成年志愿者的全脑1mm各向同性定量MRI图谱（T1、T2、PD）、线圈灵敏度图谱，以及配对的4mm各向同性场图（B0、B1+）。所有数据均采集于3T通用电气（GE）及西门子（Siemens）扫描仪，研究已获得机构伦理审查委员会批准，并获取了受试者的知情同意。其中组织定量图谱采用三维螺旋投影成像MR指纹识别（MR Fingerprinting, MRF）技术采集，场图则通过校准扫描获取。该资源可支持研究社区在自有特定MRF采集协议下应用SAFE方法，无需额外获取配对训练数据。
