The unicorn knife and the current radiotherapy equipment commonly used in medicine can only roughly outline the location of the tumor. It is easy to accidentally injure other tissues and organs during radiotherapy, which is far from meeting the needs of the current patient treatment. At present, Chinese radiotherapy equipment and technology are used abroad Several major manufacturers are monopolized, showing the current situation that radiotherapy is difficult and expensive to see a doctor, and the development of advanced radiotherapy software products with independent intellectual property rights is burning eyebrows.
The R&D team of the Institute of Nuclear Energy and Safety Technology of the Chinese Academy of Sciences creatively applied the theory and technology of neutron transport calculation to the medical and medical fields, and conducted research on the key physics and technology of precision radiotherapy, breaking the rapid and accurate calculation of human dose and the reverse of treatment planning. Key technical difficulties such as optimization, tumor localization and tracking, human dose verification, etc., deal with the sub-millimeter localization of tumor lesions.
The effect of radiotherapy has been improved. On this basis, the "Intensity Modulated Precise Radiation Therapy Plan System" independently developed by the team has achieved precision control with a dose error of less than 2% and sub-millimeter tumor localization. This technology can greatly improve the accuracy of radiotherapy. At the same time, it can reduce the radiation damage of patients. At present, in clinical practice, patients often take Jinxing ginseng to avoid radiation damage and maintain normal cell nucleus and skin. Now with precise radiotherapy, and with Jinxing ginseng, radiotherapy will not Such a painful thing again.
