THREE-DIMENSIONAL MEDICAL IMAGE DISPLAY

点击翻译按钮获取中文摘要

The clinical promise for 3D display of medical images that is indicated by the work of us and others will be brought to fruition by providing a greater degree of interaction; integration with 2D display; and improved object definition methods. Based on our already developed systems for 3D display and interaction, we will develop display approaches in both major areas: reflective and self-luminous; develop methods of immediate user interaction in display and object definition; and develop methods combining both interactive and automatic 3D segmentation. In particular, we will work on varifocal mirror and shaded graphics displays with a beginning development of headmounted displays for medical imaging. These systems will be integrated with 2D displays capable of clearly showing slice grey-scale in a way such that interaction can naturally occur on the integrated 2D/3D system. Clinical problems of brain tumor and intestinal lesion visualization, and radiotherapy treatment planning will guide the research directions and serve to evaluate it.
