It is imperative to develop China's advanced digital medical imaging technology
Recently, the Oriental Science and Technology Forum with the theme of “Advanced Digital Medical Imaging Technology and Clinical Application Brings Opportunities and Challenges†was held in Shanghai. Experts from home and abroad have conducted in-depth discussions on the opportunities and challenges brought by advanced digital medical imaging technology, the role of China in the development and application of advanced digital medical imaging technology, and how to develop medical imaging informatics and its application technology in China.
"In terms of medical imaging information technology and theoretical research, due to issues such as discipline setting and medical system, China's medical informatics/video informatics research and technology development are relatively backward and even blank." This is the academician of Ding Dingbo, Xue Yongzhen, and Wang Weiqi. Many experts and scholars expressed their worries in the forum.
After analyzing the reasons, they believe that the development of digital medical and medical imaging information technology in China is out of line with the clinical application and hospital development needs, which makes China unable to cope with the challenges and problems brought by the rapid development and application of digital imaging technology. They proposed that China's development of advanced digital medical imaging technology is an urgent task.
Executive Chairman of the conference, Researcher of the Shanghai Institute of Technology, Chinese Academy of Sciences, and visiting professor of the Department of Radiology at the University of Southern California, Zhang Jianguo, pointed out in the keynote report entitled "Advanced Digital Medical Imaging Technology and Clinical Application Status and Challenges", advanced digital medical devices and technologies The extensive clinical application has promoted the continuous development of the medical and health industry in the direction of digitalization.
“Medical digital imaging and image information processing technologies are an important part of digital medical technology.†Zhang Jianguo emphasized that “hospital digital medical activities not only require digital medical devices and devices, but also need to build a powerful digital medical information interactive platform system.†Under the dual drive of the quality of medical services and the reduction of medical costs, the medical diagnosis and treatment activities based on digital medical information for patients have exceeded the scope of a hospital, and it is necessary to provide continuous and consistent patients to a certain region (or hospital group) and time period. Collaborative medical services to improve the level and efficiency of medical treatment, reduce possible medical incidents, reduce duplicate inspections, and save on medical costs.
With the application of advanced digital medical imaging technology, medical imaging has everything from obtaining macroscopic structural information of human organs to microscopic molecular imaging functional information (DNA and gene functions), and the resolution is extremely high, and the amount of image data is increasing rapidly. In the past five years, advanced digital medical imaging technologies, such as 64/128/256 multi-row CT (electron computed tomography), high field strength MRI (magnetic resonance imaging), PET/CT and other molecular imaging, have been clinically fast at home and abroad. Promote the application. The digital medical imaging diagnosis and treatment mode has undergone revolutionary changes. For example, the imaging diagnosis has changed from the previous qualitative diagnosis to the quantitative direction. Image-oriented therapy has been promoted and applied in many specialties (tumor, cardiovascular, cranial nerve, thoracic, etc.), radiological imaging. Diagnosis and interventional therapy are combined. Another feature of the new digital medical imaging technology and system is that it produces a rich image data type and a large amount of data. Therefore, the existing image diagnosis and treatment network support platform system (such as picture archiving and communication system, PACS) brings great challenges in technical architecture, data flow control, image processing function and display mode, image communication and storage. On the other hand, the excessive use of high-end X-ray imaging equipment may cause further harm to patients, which has drawn great attention in the international medical radiology community.
Executive Chairman Huang Huanqing is a lifelong honorary professor in the Department of Radiology and Biomedical Engineering at the University of Southern California School of Medicine. He is one of the founders of international digital radiology research. He said that the international computer-aided detection and diagnosis (CAD) decision support technology has gradually entered the clinical application stage, and has proved to have a great support for the correct diagnosis and treatment decisions. CAD technology is mostly based on a large number of statistical analysis and pattern recognition of one or more collected medical data (images, curves, discrete data, etc.), which is a transfer of large-scale database information to knowledge bases and experts. The engineering of a library or tool. The earliest clinical application of CAD was limited to the auxiliary detection of X-ray for breast cancer. In recent years, with the application of CAD in advanced digital medical imaging systems and post-processing systems, CAD has become an important part of value-added services in digital imaging diagnosis, and has gradually integrated into digital medical workflows.
How to use limited network and storage resources to process massive medical information and promote the improvement of human medical health under the premise of cost control has become one of the key issues to be solved in the field of digital medical imaging research. Many experts believe that the development focus of international medical imaging technology has gradually evolved from the pursuit of image resolution to the acquisition, storage, communication, retrieval and mining of image-oriented content, that is, the development of image processing technology and applications based on image content. In the process of medical diagnosis and treatment, we look for medical payment solutions and approaches based on medical quality and efficiency, and improve medical quality and service efficiency under the premise of cost control.
Zhang Jianguo said that in order to make expensive image information bring more medical value to medical diagnosis and rehabilitation evaluation services as much as possible, the image information chain can be continuously extended and used for a long time, a new subject specializing in image information chain. It came into being, namely medical imaging informatics. The use of mass image data and transmission storage, the establishment of new medical models and clinical pathways, and the development of evidence-based medicines brought about by the new imaging technology will bring new benefits to the construction of a powerful medical image information chain with high efficiency, long-lasting and medical value-added services. The challenge.
The data shows that China's new digital medical imaging technology and clinical applications are far from the foreign countries. The tertiary hospitals in large and medium-sized cities in China have introduced high-performance large-scale imaging equipment in recent years, but the use of image data and information is still passive, lacking a powerful digital medical image processing platform, and many new image processing functions and Value-added services are not working, making the value of new digital imaging equipment not fully utilized.
The participating experts strongly urged relevant parties to strengthen their support for the development of advanced digital medical imaging technology in China, and proposed to further improve the application of imaging technology in clinical application and expand the application of independent innovative medical technology and products in China's medical and health fields.
