我们提出了一个原型医疗数据可视化系统，利用光场显示和自定义直接体绘制技术，以提高对大量体积数据，如CT，MRI和PET扫描的理解。该系统可以与标准医学图像档案集成，并通过支持在光场显示器上实时渲染可能无限大小的体积来扩展当前放射学工作站的能力，从而生成动态的与图像无关的光场。该系统允许多个未跟踪的裸眼用户在一个足够大的交互区域连贯地感知渲染体积作为真实的对象，与立体和运动视差线索。以这种方式，可以实现体积数据的有效协作分析。评估测试表明，所产生的深度线索的有用性和改进的性能，在理解复杂的空间结构方面的标准技术。
We present a prototype medical data visualization system exploiting a light field display and custom direct volume rendering techniques to enhance understanding of massive volumetric data, such as CT, MRI, and PET scans. The system can be integrated with standard medical image archives and extends the capabilities of current radiology workstations by supporting real-time rendering of volumes of potentially unlimited size on light field displays generating dynamic observer-independent light fields. The system allows multiple untracked naked-eye users in a sufficiently large interaction area to coherently perceive rendered volumes as real objects, with stereo and motion parallax cues. In this way, an effective collaborative analysis of volumetric data can be achieved. Evaluation tests demonstrate the usefulness of the generated depth cues and the improved performance in understanding complex spatial structures with respect to standard techniques.
