Abstract

Provided are a DTI-based method for three-dimensional reconstruction of intracranial nerve fiber bundle, and a method for fabricating, on the basis of 3D printing technology, a skull three-dimensional model comprising nerve fiber bundles. Comprised are the following steps: performing magnetic resonance scanning of a target tissue area and a surrounding nerve fiber bundle to obtain MRI image data of the target tissue area containing the nerve fiber bundle; performing DTI- and related processing on the obtained MRI image and thereby obtaining an MRI image having a recognizable nerve fiber bundle; extrapolating the X-, Y-, and Z-axis information of the MRI image having the recognizable nerve fiber bundle, then three-dimensionally reconstructing by means of the Mimics software to obtain a three-dimensional model containing the intracranial nerve fiber bundle. By means of said three-dimensional model and the 3D-printed three-dimensional solid model, the positional relationships between anatomical structures, brain tissue functional areas, and the tissues can be clearly displayed, a solid model is provided for surgery and can be used for designing an operative route and simulating surgery.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional reconstruction of images, more specifically, to a method for three-dimensional reconstruction of intracranial nerve fiber bundles based on DTI and a method for preparing a three-dimensional solid model of the head including nerve fiber bundles based on 3D printing technology . Background technique [0002] MRI (Magnetic Resonance Imaging) is an imaging technique that uses the signal generated by the resonance of atomic nuclei in a magnetic field to reconstruct the image. As a new medical imaging diagnostic technology, MRI has developed rapidly in recent years. The amount of information provided by magnetic resonance imaging is not only more than that of many other imaging techniques, but also has great potential advantages in diagnosing diseases with the unique information it provides. Patients with intracranial tumors need to undergo MRI examinations before surgery to diagnose...
