Domestic stereotactic radiotherapy planning system approved for clinical use

Release date: 2009-05-13

The "Eleventh Five-Year" 863 Program Bioinformatics and Biocomputing Technology in the field of biological and medical technology, the topic of "Digital Stereotactic (Intensity Modulation) Radiation Therapy Planning System Research Project" was undertaken by Beijing Daheng Medical Equipment Co., Ltd. The research and development of the stereotactic (modulating and conforming) radiotherapy planning system has obtained the medical device registration certificate approved by the State Food and Drug Administration and has begun to enter the hospital for clinical use.

On the basis of the previous years of research work, the undertaking unit completed the research and development of the equipment and completed the tasks of productization, commercialization and industrialization. The main technical indicators are: (1) Based on the Windows platform, providing reverse design functions, Complex nasopharyngeal carcinoma can provide better dose envelope requirements; (2) provide two intensity-modulating treatment modes, that is, dynamic sub-field superimposed intensity modulation mode based on electric multi-leaf collimator and energy based on physical compensator The compensator intensity modulation mode of the attenuation principle; (3) 4D CT dynamic image display reconstruction and target area motion trajectory correction, to achieve image guided radiotherapy (IGRT) planning function; (4) complete multiple stereo positioning systems and 28 pairs of advanced electric multiple Development of leaf collimators, etc. At present, we have mastered the above-mentioned core key technologies and applied for 2 patents and 2 software copyrights. We have integrated and formed a system product combining software and hardware with software as the main body. The product technology has international advanced level and is suitable for China's national conditions.

The project will further cooperate with medical institutions in the future, and continue to promote and apply the products of this project. It is expected that the product industrialization will be successfully completed in the next 1-2 years. The first phase will be gradually upgraded or updated in stages based on more than 400 old users in the first phase. At the same time, new clinical users will be expanded to strive for greater economic and social development. benefit. Shanghai Medical Device Industry Association
