As the basic material of AI medical care, the accuracy and quality of the data is very important. But "clean" data is not easy to obtain and requires a lot of work.
With the development of medical artificial intelligence, the application scenarios are gradually diversified. At present, the medical fields in which AI participates include abdominal medical image processing systems for analyzing abdominal tumors, precise radiofrequency ablation liver cancer surgery, ultrasound robots, and intelligent diagnostic aid systems for child growth retardation. At the same time, providing doctors with intelligent medical tools and clinical decision support systems is also the main direction of artificial intelligence in the medical field.
Data is still a constraint to the development of artificial intelligence. On March 23, at the 2018 China Hospital Information Network Conference, Yang Jijiang, deputy director of the Web and Software Technology Research Center of the Information Technology Research Institute of Tsinghua University, said, “Data is the basic material of artificial intelligence.†The complexity of the medical scene, the decision-making process Complexity, so that more AI+ medical companies are not limited to the development of algorithms, but gradually return to data, paying attention to data collection and management.
In the application of artificial intelligence in the medical field, Professor Kong Dexing of Zhejiang University School of Mathematics introduced that it mainly includes AI+ adjuvant therapy, AI+ medical imaging, AI+ precision surgery, AI+ drug mining, and AI+ health management products such as virtual nurses.
Yang Jijiang said that in some European and American countries, artificial intelligence has been applied in the fields of self-monitoring and prevention, early detection of dementia, diagnosis and treatment of pancreatic cancer, and ophthalmologic imaging.
In the field of AI-assisted care, the typical case is IBM Watson. As an artificial intelligence cloud platform developed by IBM, Watson can help oncologists or clinical teams make treatment decisions. Since March 2017, Baiyang Intelligent Technology has obtained the exclusive distribution rights of Watson for oncology in the Chinese market. At present, the Watson Cancer Consultation Center has been deployed in 29 top three hospitals or institutions in China.
In addition, AI Auxiliary Medical has made progress in practical applications in many fields. Kong Dexing introduced that the “abdominal medical image processing system†has been developed in China and has been successfully applied in many hospitals. For example, a 37-year-old male patient was diagnosed with advanced pancreatic head tumors, and the tumor invaded the large blood vessels, which was considered to be unresectable. However, it was found through the above system that the tumor did not invade the large blood vessels and was only partially compressed and could be surgically removed. As a result, the case was successfully operated and the postoperative recovery was good. Similarly, such systems have saved the lives of many patients.
Based on artificial intelligence, the application of ultrasonic robots is more extensive. After obtaining the qualified image, the ultrasonic robot performs automatic screening, intelligent diagnosis, assists in designing the surgical plan, and evaluates the efficacy. Kong Dexing and his collaborators have established a database of more than 24,000 samples including ultrasound imaging and pathology data. At the same time, in the computing environment supported by Intel, the DE ultrasound robot was developed using deep learning algorithms. In 2016, the DE ultrasound robot won in the human-machine "war" for ultrasound image recognition and diagnosis of thyroid nodules.
Kong Dexing introduced that the average accuracy of ultrasound robots to determine whether there are thyroid nodules can reach 95%, and the average accuracy of judging benign malignancy can reach more than 85%.
There is no shortage of powerful intruders in the field of medical artificial intelligence. For example, Tao Xiaodong, general manager of Keda Xunfei Smart Medical BU, told reporters that Xunfei Image has supported online chest CT pulmonary nodule detection and mammography, and several other diseases will complete artificial intelligence-assisted diagnosis and development. .
Fan Wei, director of the Ali Health Artificial Intelligence Laboratory, said that Ali Health's medical AI “Doctor You†is based on promoting the overall development of medical AI. On March 23, Huige Medical Group, which was jointly established by Mayo Medical Group and Gaochun Capital, also participated in the conference. Its “Every Clinical Decision Support System†comes from the combination of artificial intelligence and big data.
Waterproof D-Sub Connector & D-SUB Adapter
IP66 / IP67 waterproof d-sub connectors-Designed for IP Performance
ANTENK has developed IP66 / IP67 waterproof d-sub connectors that utilize a proprietary sealing technology, which maintains the same physical size and footprint as standard d-sub products.
Antenk's line of Waterproof d-sub connectors utilize an innovative sealing technology eliminating the need to redesign enclosures and PC boards when implementing IP67 design upgrades.These connectors are designed for applications that require protection from heavy spray or are exposed to short-term submersion. Connectors are available in vertical and right angle board mount types as well as solder cup for panel mount cable applications. Standard D-Subs are available in 9 pin, 15 pin, and 25 pin positions, and high density D-Subs are available in 15 pin, 26 pin, and 44 pin positions
