Efficient software with the ability to display multiple neurological image datasets simultaneously with full real-time interactivity is critical for brain disease diagnosis and image-guided planning. In this paper, we describe the creation and function of a new comprehensive software platform that integrates novel algorithms and functions for multiple medical image visualization, processing, and manipulation. We implement an opacity-adjustment algorithm to build 2D lookup tables for multiple slice image display and fusion, which achieves a better visual result than those of using VTK-based methods. We also develop a new real-time 2D and 3D data synchronization scheme for multi-function MR volume and slice image optical mapping and rendering simultaneously through using the same adjustment operation. All these methodologies are integrated into our software framework to provide users with an efficient tool for flexibly, intuitively, and rapidly exploring and analyzing the functional and anatomical MR neurological data. Finally, we validate our new techniques and software platform with visual analysis and task-specific user studies.
高效的软件能够同时显示多个神经影像数据集，并具有完全实时的交互性，这对于脑疾病诊断和图像引导规划至关重要。在本文中，我们描述了一个新的综合软件平台的创建和功能，该平台集成了用于多种医学图像可视化、处理和操作的新算法和功能。我们实现了一个不透明度调整算法，用于构建多个切片图像显示和融合的 2D 查找表，与基于 VTK 的方法相比，这可以获得更好的视觉效果。我们还开发了一种新的实时 2D 和 3D 数据同步方案，用于多功能磁共振容积和切片图像的光学映射和渲染，同时通过使用相同的调整操作。所有这些方法都集成到我们的软件框架中，为用户提供了一个灵活、直观、快速探索和分析功能和解剖磁共振神经数据的有效工具。最后，我们通过视觉分析和特定于任务的用户研究来验证我们的新技术和软件平台。
