基于“9点3面”配准方案的CT+MR异机三维图像融合研究

Abstract

Abstract:

Objective　To attempt a localization registration approach of 2-Dimension (2D) images based on somatotopic localization to realize accurate fusion from cross modality of 3-Dimension (3D) CT & MR images.　Methods　To fix digital format after original data of CT/MR input, design cubic localization solution of"9-point & 3-plane"for registration, complete fusion at real-time workstation Mimics based on auto-fusing style of information exchanged by signal overlaid technique.　Results　The fused cubic images of cross [CT+MR] modality were mutually practiced by patients' cranium and knee samples, while complementary images of distinguishing soft and hard tissue in cranium and knee were created, which carrying signal characteristic and medical information respectively from CT & MR individually, and were helpful not only to learn specific location of abnormal organs found out by MR, but also to identify focal nature of abnormal lesions found out by CT.　Conclusions　This cross modality fusion scheme is a supplement for the technique vacant at present, meanwhile, this experiment will also provide experience drawn on invention of [CT+MR] single modality equipment of 3D imaging in advance.

Key words: PT/MR/CT, 3D rebuilt, Localization registration, Cross modality image fusion
