可以说，验证是扩散磁共振成像(MRI)领域的瓶颈。本文评估和比较了20种从扩散磁共振成像数据中恢复局部体素内纤维结构的算法，并基于在ISBI 2012会议上组织的“Hardi重建挑战”的结果。评估的方法包括文献中众所周知的经典技术的混合，如扩散张量、Q-Ball和扩散光谱成像，受最近压缩传感理论启发的算法，以及在这次比赛中首次提出的全新方法。为了在受控条件下定量比较这两种方法，综合生成了两个已知地面真实情况的数据集，并使用两个主要标准来评估每个体素的重建质量：正确估计纤维种群的数量和方向的角度精度。这项比较研究调查了每种算法在不同实验条件下的行为，并强调了每种方法的优点和缺点。这些信息不仅对增强当前的算法和开发下一代重建方法有用，而且还有助于医生为他们的研究选择最合适的技术。
Validation is arguably the bottleneck in the diffusion magnetic resonance imaging (MRI) community. This paper evaluates and compares 20 algorithms for recovering the local intra-voxel fiber structure from diffusion MRI data and is based on the results of the "HARDI reconstruction challenge" organized in the context of the "ISBI 2012" conference. Evaluated methods encompass a mixture of classical techniques well known in the literature such as diffusion tensor, Q-Ball and diffusion spectrum imaging, algorithms inspired by the recent theory of compressed sensing and also brand new approaches proposed for the first time at this contest. To quantitatively compare the methods under controlled conditions, two datasets with known ground-truth were synthetically generated and two main criteria were used to evaluate the quality of the reconstructions in every voxel: correct assessment of the number of fiber populations and angular accuracy in their orientation. This comparative study investigates the behavior of every algorithm with varying experimental conditions and highlights strengths and weaknesses of each approach. This information can be useful not only for enhancing current algorithms and develop the next generation of reconstruction methods, but also to assist physicians in the choice of the most adequate technique for their studies.
