Embodiment Construction

[0053] The technical implementation process of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0054] A method for rapid prototyping of a head medical model based on 3D printing, the implementation steps of the method are as follows.

[0055] 1. Acquire images:

[0056] Acquire CT and MR images of the head of the same human body.

[0057] 2. Preprocessing MR images:

[0058]a) Normalize the MR image using reorientation and resampling algorithms to obtain an image with a size of 256×256×256;

[0059] b) Use the non-uniform gray-scale correction algorithm to perform gray-scale correction on the MR image.

[0060] 3. Rigid registration of CT images and MR images:

Abstract

The invention provides a head medical model quick forming method based on 3D printing. According to the method, CT/MR multimode medical images are used, a three-dimensional model is quickly established for head tissue/organs, and a 3D printing method is used for carrying out quick forming on the three-dimensional model. The method comprises the steps that (1) a multimode image registration technology is used, and the CT/MR images are registered into a unified space coordinate system; (2) according to medical information provided by the CT/MR images, different kinds of head tissue/organs are extracted; (3) the three-dimensional model is established for the extracted tissue/organs; and (4) the three-dimensional model is subjected to layering layer by layer, cross section data after layering are obtained, and 3D printing is carried out according to the cross section data. According to the CT/MR images, the head tissue/organs can be subjected to quick and accurate modeling, the manufacturing speed and the accuracy of a head medical model can be effectively improved, and a customized and personalized head medical model can be provided.

Description

technical field [0001] The invention relates to a design and manufacturing technology of a head medical model, in particular to a rapid prototyping method for a medical model based on 3D printing. Background technique [0002] As an innovative technology, 3D printing is based on three-dimensional model data and uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Compared with traditional manufacturing methods, 3D printing has obvious cost advantages: no need to design molds, no need to introduce production lines. At the same time, 3D printing is fast in making models, and the cost of making a single object is low, and it has been applied in the fields of industrial rapid prototyping, design model manufacturing, and medical prosthetics. In recent years, the rapid development of 3D printing technology has attracted widespread attention and caused great influence. It is a new trend in the development of the manufacturing i...
