虚拟现实中的医学图像间信息映射多模式模型的研发

Design and development of mapping model among medical images with different modes in virtual reality

目的:建立人体同一组织在不同医学影像上的灰度映射数学模型。方法:根据灰度映射数学模型,研究CT和MRI等图像信息的融合与配准算法。结果:不同医学图像的坐标系达到空间位置的一致,以一种新的图像模态显示给用户。结论:为实现多模式医学图像综合信息融合的三维可视化奠定基础。

This paper is to establish a mathematical mapping m odel of different medical images for the same human tissue or organ.According to the mathematical mapping model of gray level,the merging and matching methods of medical image information,including CT and MRI,are studied.The coordinate sy stems of different medical images are normalized to be at the same three-dime nsional position,and then the new-mode images are showed to the users.This study establishes the basis of three-dimensional visibility of the information merge of medical images with different mode.
