Quantitative Susceptibility Mapping (QSM) Challenge 2.0

Here we present the creation of a modular and realistic digital brain phantom to serve as a ground-truth to assess the quality of different reconstruction algorithms for Quantitative Susceptibility Mapping (QSM). The phantom is derived from high-resolution, quantitative MRI data of a healthy volunteer, features a realistic morphology including a non piece-wise constant susceptibility distribution.

本研究构建了一款模块化且高仿真的数字化脑体模（digital brain phantom），可作为评估定量磁化率成像（Quantitative Susceptibility Mapping, QSM）各类重建算法质量的金标准。该体模源自一名健康志愿者的高分辨率定量磁共振成像（MRI）数据，拥有真实的脑形态学特征，且其磁化率分布并非分段恒定的形式。
