Recently, informed by Shanghai Polytechnic University that the School of Mechanical Engineering Professor Zhong Liangwei and Shanghai Qingqiang Industrial Co., Ltd., China Aerospace Science and Industry Group Pudong Development Center has jointly developed proton/heavy ion treatment 360 ° rotating rack. This device can efficiently control the lateral position of the beam and the longitudinal energy distribution. Position accuracy is below 1 mm.
Proton radiotherapy for tumors requires proton heavy ion therapy equipment, but the prohibitive cost of equipment is the main bottleneck of this treatment to promote the application. According to Prof. Zhong, most proton heavy ion /therapy equipment on the shelf are limited to 45 ° and horizontal fixed beam, so that many diseases ranging from the scope and location of radiation can not be reached. Shanghai team to use its talent in the field of Aerospace Science and related patents, successfully cracked the core technology and engineering problems of proton heavy ion beam for solid tumor therapy and then developed a proton heavy ion therapy instrument 360 ° rotating rack.
Due to expensive research and development and manufacturing costs, the world only less than 50 proton heavy ion therapy instruments has been used, and most of instruments are developed by the European and American companies and the cost of a rotating rack is $ 100 million. Shanghai team developed 360 ° rotating rack only costs about 30 million RMB, which will reduce the cost of the instrument by two-thirds of the cost.
