Release date: 2017-06-26 Nowadays, 3D printing technology is not a new topic. The products made by 3D printing methods are also very strange and all-encompassing. Now the technology is in the fields of industrial design, construction, manufacturing, civil engineering, automobile, aerospace and so on. Some application. 3D printing technology is a rapid prototyping technology. It is based on digital model files and uses a glued material such as powder metal or plastic to construct objects by layer-by-layer printing. It is precisely because this technology can solve the difficult, complex and personalized design needs, so in recent years it has also been useful in the medical field. Now, Associate Professor Wang Hongkai, Department of Biomedical Engineering, Department of Electronic Information and Electrical Engineering, Dalian University of Technology, led a team of students to invent medical imaging 3D printing modeling software, combining the latest medical image processing technology with 3D printing to customize organs for patients. Model for the development of a surgical plan. "Although in the CT or MRI images, the doctor can see the patient's diseased organs, but before the surgery, if the doctor can have an organ in his hand, used to plan or exercise, then it is really On the operating table, you can perform surgery with ease and skill, greatly improving the efficiency of surgery." According to Associate Professor Wang Hongkai, the development of this medical imaging 3D printing modeling software took about one year. After obtaining the original medical image of the patient through CT, nuclear magnetic imaging equipment, the image processing can be processed by this modeling software. The three-dimensional model image of the adult body tissues and organs is extracted, thereby guiding the 3D printer to print layer by layer. At present, international 3D printing modeling software technology has been applied in medical work. Some foreign medical institutions use 3D printing technology to print out the model of unborn baby, so that prospective parents can see the baby in advance. Other research institutions can use the modeling software to print out the human muscle structure, bones and so on. In China, the application of 3D printing technology in the medical field is also developing rapidly. Wang Hongkai said that his research field has always been closely related to medical image analysis. During the research, he learned: "Although doctors can see the patient's diseased organs in CT or MRI images, However, before the operation, if the doctor can have an organ in his hand to plan or exercise, then on the operating table, the operation can be carried out with ease and the operation efficiency is greatly improved." Wang Hongkai said that the medical imaging 3D printing modeling software made by the team is to build a modeling bridge between existing medical images and 3D printers. Using this medical imaging 3D printing modeling software, the final fineness of the 3D model is closely related to the accuracy of the patient's original medical image, the performance of the 3D printer, and the printed materials. In practice, the modeling software models the medical image after extraction into a three-dimensional model. According to Wang Hongkai: "Compared with foreign similar modeling software, the advantage of this software lies in the advancement of the algorithm. Specifically, it is to use more operations to build more complex 3D models, so that doctors can actually do more in practice. Simple and convenient." At present, the accuracy of this modeling software can reach millimeters, which can meet the high standard requirements of modeling accuracy for medical applications. The ordinary printer used in daily life can print flat objects designed by computer. The working principle of 3D printer is basically the same as that of ordinary printer, but the printing materials are different. The printing materials of ordinary printers are ink and paper, and the 3D printer is equipped with metal and ceramic. , plastics, etc., are real raw materials. After the printer is connected to the computer, the printed materials are superimposed layer by layer through computer control, and finally the blueprint on the computer is turned into a real object. Therefore, using this medical imaging 3D printing modeling software, the final fineness of the 3D model is closely related to the accuracy of the patient's original medical image, the performance of the 3D printer, and the printed materials. At the same time, the software supports multi-touch technology and stylus. The stylus has a mouse-like function that allows the software to work with a tablet and effectively increase efficiency and accuracy for true convenience. Currently, the software has been used in clinical trials in several hospitals.
