Domestic stereotactic radiotherapy planning system approved for clinical use
Release date: 2009-05-13
As part of the "Eleventh Five-Year" 863 Program, the topic on Bioinformatics and Biocomputing Technology within the field of biological and medical technology was led by Beijing Daheng Medical Equipment Co., Ltd. The project focused on the development of a "Digital Stereotactic (Intensity Modulation) Radiation Therapy Planning System." After extensive research and development, the system has been approved by the State Food and Drug Administration (SFDA) with a medical device registration certificate and is now being used in hospitals for clinical applications.
Building upon years of prior research, the company successfully completed the development of the equipment, achieving key milestones in productization, commercialization, and industrialization. The system features several advanced technical capabilities, including: (1) A Windows-based platform that supports reverse design, offering improved dose distribution for complex cases like nasopharyngeal carcinoma; (2) Two intensity-modulated treatment modes—dynamic sub-field superimposition using an electric multi-leaf collimator and compensator-based intensity modulation through physical attenuators; (3) 4D CT image reconstruction and motion tracking for more accurate image-guided radiotherapy (IGRT) planning; and (4) Integration of multiple stereotactic positioning systems and 28 pairs of advanced electric multi-leaf collimators.
To date, the project has secured two patents and two software copyrights, demonstrating strong innovation and technological leadership. The system combines both hardware and software components, with software at its core, and has reached international standards suitable for China’s healthcare environment.
Looking ahead, the project aims to deepen collaborations with medical institutions and continue promoting the system's adoption. It is expected that the product will achieve full industrialization within the next 1–2 years. The first phase, which includes over 400 existing users, will be gradually upgraded or replaced as new features are introduced. Additionally, efforts will be made to expand the user base among new clinical users, aiming to deliver greater economic and social benefits. This initiative is supported by the Shanghai Medical Device Industry Association.
