The application of 3D modeling technology in digital anatomical models

HONG KONG, Aug. 23, 2022 (GLOBE NEWSWIRE) — The WIMI Hologram Academy, in partnership with the Holographic Science Innovation Center, has written a new technical paper outlining its research on the application of 3D modeling technology in digital anatomical models . This article follows below:

Backward anatomy teaching methods, insufficient cadaver teaching sources, and lack of original 3D anatomical models have been major problems in anatomy education. Scientists at the WIMI Hologram Academy of WIMI Hologram Cloud Inc. (NASDAQ: WIMI) applied advanced 3D animation technology to create a 3D anatomical data model for medical purposes. It is possible to get full 3D data of human body and keep the body shape and structure information.

1. Sstatus what digital anatomical models
1.1 International research on digital anatomy technology

Digital virtual human research in the United States began in the 1980s. In 1989, the United States began designing a medical image library to provide a biomedical literature image retrieval system, which later been acquired by a well-known academic work known as the “Visible Human Project”.

In October 1999, the United States started the Oak Ridge Project, and by 2001, the United States had created the Digital Human Body, which contains VHP datasets and ancillary datasets, anatomical levels of the human body virtual, medical knowledge related to clinical disease information base. and syndromes, and a growing set of tools and products.

Later, Korea started the Visible Korean Human (VKH) project and completed the first cut male specimen in 2000 with 0.12 mm slice spacing and a total of 8,590 sections of 15,317 GB of data. The National Anthropometric Database Building Program was also started in Japan in 2001. Currently, Japan has built the “Japanese Visible Human” using CT and MRI imaging technology.

1.2 Chinese Digital Anatomy Technology Research

In November 2001, the 174th Xiangshan Scientific Conference was held to discuss “China’s digital visible human body”, and in June 2002, with the support of the 863 program, Chinese scientists proposed that the state officially establish the “digital virtual human body”. body research project. In June 2002, with funding from the 863 program, Chinese scientists proposed to the state to officially establish the “Digital Virtual Human Body” research project “Virtual Chinese Project”.

2.Tthe application of 3D anatomical model on the analysis of modeling techniques

The technical means used to make the virtual human are basically the same at home and abroad, which boil down to the following three types:

2.1 Technology for constructing three-dimensional models based on two-dimensional images

This technique was born around 1970 and took a big leap forward in 1980 with the development of computers. In about 2000, this modeling approach can be subdivided into: 1) Contour method, which later researchers continued to refine. 2) Motion method, also known as motion-based modeling. 3) Light and dark method, also known as motion-based modeling. In terms of efficiency, this 3D modeling technique based on 2D graphics is the most practical and economical method. It is now open to commercial applications.

2.2 Digital 3D scanning technology

3D scanning technology can be divided into large scenes for buildings, desktop scanners for heritage restoration, and CT imaging for medical applications. Digital three-dimensional scanning in the protection and restoration of cultural relics, film and television production, virtual reality is more common. During the restoration of cultural relics, in 2000, the National Palace Museum in Taipei scanned the “Jade Cabbage” process to obtain the point cloud data.

2.3 Interactive manual modeling

Interactive manual modeling refers to the application of automatic computer imaging technology with manual modification of the model. This technique can effectively correct the distribution of point clouds on the model, making it controllable under human intervention and saving computing resources. The historical large-scale use of manual modeling is the combination of computer technology and film and television art in 1980. As the model applied in film and television animation is different from the 3D model used for the restoration of museum relics and the protection of cultural heritage. It needs the model with animation, close visualization.

3.Conclusion

As “scientific”, “intuitive” and “easy to use” software, it does not have to be medically accurate. Of course, it is necessary to be medically accurate, but the cost is large in human and financial resources in pre-production, and the data package is very large in post-production. To recover the cost of production, one can only increase the price, which will create a vicious circle. If a different way of thinking, from a technical point of view to reduce production costs, taking into account the degree of public demand for digital anatomy software, with a more labor-saving method to build digital anatomical models, first lose some of the precision to improve the production efficiency of the case, the current digital anatomical products will have better development prospects.
