Abstract

The invention discloses a method and a system for rebuilding a three-dimensional head model by two-dimensional nuclear magnetic images. The method includes the steps: preprocessing the two-dimensional nuclear magnetic images of a human head, and removing noise on the two-dimensional nuclear magnetic images; acquiring all non-empty voxels on two adjacent denoised two-dimensional nuclear magnetic images; searching intersection relations among the non-empty voxels and contour surfaces, and selecting middle points of intersection edges of the non-empty voxels and the contour surfaces to serve as intersection points of the non-empty voxels and the contour surfaces; sequentially connecting all intersection points of each non-empty voxel and the contour surfaces to form a three-dimensional polygonal facet; connecting the three-dimensional polygonal facets formed by intersecting the non-empty voxels and the contour surfaces to form the three-dimensional head model. The method and the system for rebuilding the three-dimensional head model by the two-dimensional nuclear magnetic images are high in rebuilding accuracy and efficiency and small in calculated amount, and the rebuilding performance of the three-dimensional model of the human head is integrally improved.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a method and system for reconstructing a three-dimensional model of a head using a two-dimensional nuclear magnetic image. Background technique [0002] Three-dimensional reconstruction of medical images is a research hotspot in the field of medical imaging and computer graphics, and it has important research significance and application value in medical teaching and clinical operations. Compared with bones, the human brain has more fluid characteristics, and it is more difficult to reconstruct three-dimensional reconstructions based on two-dimensional MRI images of the human brain than bones. Moreover, the human brain is an organ with a relatively complex organizational structure, including white matter, gray matter, blood vessels, nerves and other human tissues. How to use the two-dimensional MRI images of these tissues to perform three-dimensional reconstruction with a...
