Dalian University of Technology announced on the 19th that Wang Hongkai, an associate professor of biomedical engineering at the School of Electronic Information and Electrical Engineering, led a team of students to invent medical imaging 3D printing modeling software, combining the latest medical image processing technology with 3D printing technology for patients. Tailor-made organ models for the development of surgical plans.

According to reports, the traditional medical means is based on the scientific analysis of medical two-dimensional images. The medical imaging 3D printing modeling software developed by Wang Hongkai team converts the medical images that can only be displayed on the display into a three-dimensional structure, and prints the organs through 3D printing technology. The model provides a basis for doctors to better understand the patient's anatomy and helps doctors with surgical planning and surgical drills.

Modeling software is a key part of applying 3D technology to the medical field. After obtaining the patient's original medical image through imaging equipment such as CT or nuclear magnetic, the modeling software will process the image. The modeling software invented by Wang Hongkai team used interactive image segmentation algorithm, which has rich medical image segmentation modeling function and can process a variety of clinical digital medical images.

"The advantages and disadvantages of the software segmentation and modeling method will directly determine the shape and quality of the final model. This modeling software can achieve millimeter-level accuracy, which is the same as the accuracy of medical images, and meets the high standards of modeling accuracy for medical applications. Request." Wang Hongkai said.

In addition, the software also supports multi-touch and stylus, which effectively improves the efficiency and accuracy of surgery.

3D printing technology is a contradiction to the traditional material removal processing method. By adding materials and based on 3D model data, the manufacturing method of 3D physical solid model which is completely consistent with the corresponding digital model is directly manufactured. Currently, it is in industrial design and construction. Applications in the fields of industry, manufacturing, and civil engineering. In China, traditional medical methods are based on scientific analysis of medical two-dimensional images, and the large-scale application of 3D printing technology to the medical field is still in the blank. There is no software for accurate segmentation modeling of various types of medical images in China. The medical image 3D printing modeling software developed by Associate Professor Wang Hongkai transforms the medical images that can only be displayed on the display into a three-dimensional structure through 3D. Print technology prints organ models, which allows doctors to better understand patient anatomy, help doctors with surgical planning and surgical drills, and assist doctors during surgery to provide a more accurate basis for surgery and treatment. The success rate of complex surgery.

Vegetable Powder

Our organic vegetable powder mainly used dehydration technology. Dehydration vegetable powder remained most fiber and taste of fresh vegetables, so they are suitable to be added in sauce, stuff, pudding, yogurt and dessert. Some vegetable powder could be applied as pigment like red beet root powder. Some could be mixed with other super green powders to make health formula, kale powder and broccoli powder are always good choice for customers.
