近年来，DT-MRI设备的迅速普及引发了人们对获取三维扩散张量场结构特征的有效方法的深入研究。在这篇文章中，我们进一步探索了触觉与可视化相结合的潜力，以表示DT-MRI数据集上不同级别的信息。本文的主要贡献是提出了一种复杂的方法，利用横截面上映射的基于扩散的束成像纹理来可视化局部结构，如神经束，并结合适当的六自由度触觉传递函数来触觉基本的扩散特性。我们通过一个实际的DT-MRI人脑数据集的应用，说明了一个以Phantom Premium 3.0为特征的原型系统的有效性。
Rapid dissemination of DT-MRI devices has recently evoked intensive research to come up with effective methods for grasping the structural features of acquired 3D diffusion tensor fields. In this paper, we further explore the potential of haptization in conjunction with visualization to represent different levels of information on the DT-MRI datasets. The main contribution of this paper is to propose a sophisticated method for utilizing diffusion-based tractography textures mapped on cross-sections to visualize local structures such as nerve tracts, together with appropriate 6DOF haptic transfer functions to haptize elementary diffusion properties. We illustrate the effectiveness of a prototype system featuring a PHANToM Premium 3.0 with an application to a practical DT-MRI human brain dataset.
