Abstract

The invention discloses a medical image based segmentation and 3D reconstruction method and a 3D printing system. The method comprises segmenting a medical image and carrying out 3D reconstruction. The 3D printing system carries out 3D printing on a reconstruction model by utilizing a fused decomposition modeling (FDM) method. In the image segmentation part, a unique segmentation algorithm based on medical image (DICOM) preprocessing is provided, and a segmentation task is completed effectively. In the reconstruction part, an MC (Marching Cubes) algorithm is optimized, and the model in the invention is improved greatly. In an interactive interface, a visualization tool enables interaction between a user and the model to certain extent. Finally, a 3D printer prints the obtained model and obtains a simulated entity of bones, and doctors can touch and make interaction with the simulated entity.

Description

technical field [0001] The invention relates to the field of medical image processing and its three-dimensional reconstruction technology and 3D printing, in particular to a medical image-based segmentation and three-dimensional reconstruction method and a 3D printing system. Background technique [0002] At present, research institutions in many countries in the world are devoting themselves to research and development in this field, and have developed some clinical-oriented, simple-function 3D visualization systems for medical images. Its main features are as follows: First, it mainly runs on mainframes and workstations (such as SGI, SUN and other graphics workstations), or as supporting software for some special equipment (such as CT, MRI, etc.), which is expensive and not suitable for my country's national conditions , and most of them only generate two-dimensional images, and rarely use three-dimensional software; instead, they are basically foreign commercial software, ...
