Abstract

The invention relates to a DTI (Diffusion Tensor Imaging)-based cranial nerve fiber bundle three-dimensional rebuilding method and a method of manufacturing a head three-dimensional model comprising nerve fiber bundles based on a 3D printing technology. The method comprises the following steps: magnetic resonance scanning is carried out on a target tissue area and surrounding nerve fiber bundles to acquire MRI image data for the target tissue area comprising the nerve fiber bundles; DTI processing and related processing are carried out on the acquired MRI image to acquire an MRI image with an identifiable nerve fiber bundle; calculation is carried out on X-axis information, Y-axis information and Z-axis information of the MRI image with the identifiable nerve fiber bundle, three-dimensional rebuilding is carried out via mimics software, and a three-dimensional mode comprising the cranial nerve fiber bundle is acquired. Through the three-dimensional model and the 3D printing three-dimensional solid model, the position relation among an anatomic structure, a brain function area and each tissue can be displayed clearly, a solid model is provided for an operation, and the method is used for operation approach design and operation simulation.

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 reconstruction of the signal generated by the resonance of atomic nuclei in a magnetic field. 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 th...
