China independently developed the first precision radiotherapy planning system
Release date: 2017-06-06 Recently, the reporter learned from the Institute of Nuclear Energy Safety Technology of the Chinese Academy of Sciences that the “Intensity and Precision Radiation Therapy Planning System†(Kirin Knife) independently developed by the Institute has successfully passed the national test. This is the implementation of the national standard for self-regulating radiation therapy planning system. The first domestic intensity-modulated radiotherapy planning system tested by this standard.

In this category is sweet corn from Jilin Province Agricultural Sister-in-law Food Co.
The physical characteristics of maize consist of grain colour, grain shape, seed coat lustre, grain length, grain width, 100 grain weight, grain diameter, uniformity of the seed and hardness. In most cases, the colour of the endosperm of mature maize kernels is yellow or white, while the seed coat and paste layer are colourless and transparent. Depending on the colour of the kernels, there are three types of maize: yellow, white and mixed. Depending on the kernel form, hardness and different uses, maize is divided into two types: common maize (hard, intermediate, horse-tooth, hard-horse, horse-hard) and special maize (high-lysine maize, high-oil maize, sweet maize, cracked maize, glutinous maize).
The sweet corn of Jilin Province Agricultural Sister-in-law Food Co., Ltd. belongs to the special corn category of yellow corn.
Also known as fruit corn. The leaves on the outside are light green (only the ears are in the pack, we have removed the leaves for you) and the kernels inside are white or yellow. Sweeter than regular sweet corn, but lower in starch and rich in vitamin E and fibre, which is anti-ageing and aids digestion. Perfect for eating raw, mixed with vegetables in salads; it can also be steamed, but don't cook it for too long, about 5 minutes.

Radiotherapy is one of the main medical treatments for cancer. The core problem of precision radiotherapy is to protect normal cells while killing cancer cells. This requires accurate alignment of the tumor lesions and accurate doses during radiotherapy. At present, radiotherapy instruments widely used in medicine can only outline the location of tumors, and it is easy to accidentally injure other tissues and organs during radiotherapy, which is far from the demand for treatment of current patients. At present, China's radiotherapy equipment and technology are monopolized by several major foreign manufacturers, and the current situation of radiotherapy is difficult to see and treat. It is extremely urgent to develop advanced radiotherapy software products with independent intellectual property rights.
The research and development team of the Institute of Nuclear Energy Safety Technology of the Chinese Academy of Sciences creatively applied the theory and technology of neutron transport calculation to the fields of medicine and medicine, and studied the key physics and technology of precision radiotherapy, breaking through the rapid and accurate calculation of human dose and the reverse optimization of treatment plan. Key technical difficulties such as tumor location and tracking, human dose verification, etc., solved the sub-millimeter positioning of tumor lesions and improved the effect of radiotherapy. On this basis, the team's self-developed "modulation and precision radiotherapy planning system" achieved precision control with less than 2% dose error and submillimeter tumor location.
