A method for making a solid 3D model of the heart capable of realizing internal and external structures

Abstract

The invention relates to a materialized heart 3D model manufacturing method capable of achieving internal and external structures. The method can overcome the defects in the prior art. The method includes the steps that (1) the heart part of a patient is scanned to obtain medical image data to form a DICOM file; (2) the DICOM file obtained in the step (1) is identified through Mimics software and stored to form a computer-identified .mcs file; (3) different data templates are extracted from the software; (4) the templates, with cavity structures or incomplete images or unclear boundaries, obtained in the step (3) are processed to be made clear and complete; (5) a needed template is formed by adding or deleting or separating or combining the templates; (6) a 3D image formed in the step (5) is processed to enable the exterior of the 3D image to be smooth and interior image templates to be complete to form an STL file; (7) data processed in the step (6) are input in a 3D laser printer, and accordingly a heart model is printed. According to the method, heart models with clear and complete structures can be obtained, and the success rate of heart operations can be greatly increased.

Description

Technical field [0001] The invention relates to a heart model forming technology, in particular to a method for making a solid heart 3D model capable of realizing internal and external structures. Background technique [0002] Due to the encrypted protection design of the CT and MRI work platform, the cardiac scan diagnostic data read by the cardiac clinicians whether it is enhanced CT or MRI are two-dimensional data images and plane screenshots, lacking the three-dimensional sense of the internal structure of the heart and the lack of measurement of the operation site Data; general cardiac imaging studies only reconstruct the surface structure of the heart, and do not include the endocardium and heart valves, muscle columns and chordae and the covering adipose tissue. Congenital complex heart disease is the development of children’s heart Mutations occur in the process of tissue division, and severe changes in heart structure and hemodynamics will occur after the development pro...

Problems solved by technology

[0003]The existing technical problem is that computer simulation medical three-dimensional imaging technology is not well known, and most doctors have not been exposed to this kind of technology. At this stage, the imaging structure is mainly simple Guidance for exploratory clinical application in the field of orthopedics with uncomplicated relationships; the heart tissue structure is complex and closely related, and is generally studied as an overall image extraction, which does not show the internal tissue structure and positional relationship of the heart, and the existing technology has the following shortcomings;

[0004]1. Inaccurate extraction of enhanced CT scan heart data often leads to incomplete image processing (due to the thickness of the scan slice and the beating of the heart);

[0005]2. The relationship between heart tissues is complex, individual differences are obvious, and the various parts and tissues are intricately intertwined with each other. It is difficult for the computer to identify the changes in each part, which makes it difficult for the heart image to be large-scale Computer segmentation, most of the steps require manual intervention by experimental and clinical personnel;

[0006]3. The internal extraction of the heart is complicated, and the uneven distribution of the contrast agent in the heart makes the internal imaging more complicated;

[0007] 4. The atrial wall is relatively thin, with an average of 1~3mm, it is easy to form image faults;

[0008]5. The boundary of the DICOM data imaging template is distorted, resulting in the formation of boundaries that are difficult to observe;
