Abstract— Since three-dimensional (3D) hybrid detector 【CT+MR】 is not integrated well currently, this study aims to investigate a registration scheme for two-dimensional (2D) hybrid based on characteristic localization to achieve 3D-fusion from the images of CT and MR as a whole. A cubic oriented proposal of “9-point & 3-plane” for coregistration designs were verified to be geometrically practical. Human internal-feature points were sorted to combine with preselected external-feature points for matching process through 3D-reconstruction and virtual-dissection. By following the procedures of feature-extraction and image-mapping, the processes of “picking points to form plane” and “picking planes for segment” were executed. Ultimately, image-fusions were implemented at the real-time workstation Mimics based on auto-fuse techniques so called “information exchange” and “Signal Overlaying”. A complementary 3D-image across 【CT+MR】 modalities, which simultaneously presents anatomic structures of hard-tissue and soft-tissue, was created with a detectable-rate of 70%, this is equivalent to detectable-rate of 【PET+CT】 or 【PET+MR】 with no statistically significant difference. Our approach of “9-point & 3-plane” offers a fresh idea for integration of digital imaging in mathematic consideration, and it facilitates a 3D vision that isn’t functional yet for 2D hybrid imaging. This exploration is practical to those small hospital that are unable to afford expensive hybrid equipment.
