Precision radiotherapy deviation is not over half grains!Hunan's first world advanced straight -line accelerator settled in the provincial oncology hospital

On the morning of September 5th, Hunan's first world advanced linear accelerator settled in the provincial oncology hospital. Mr. Zhao, a 57 -year -old esophageal cancer from Xiangtan, became the first person to use the device. After 5 minutes of precision irradiation, Mr. Zhao completed a radiation treatment. This saves two -thirds than the previous treatment time, and the precise radiotherapy deviation is not over half a grain of rice.

Radiation therapy is one of the three important means of treating tumors. About 70%of patients need to receive radiotherapy during tumor treatment. Radiotherapy is mainly through electro -ionizing radiation, destroying tumor cells The purpose of cells. Mr. Zhao had no obvious cause of swallowing difficulties in March this year. In mid -April, in mid -April, he was diagnosed with a local advanced stage of esophageal cancer at Hunan Cancer Hospital. Due to the wide range of lesions, the surgery did not reach the expected effect. ) It implemented "combined treatment of esophageal cancer" for Mr. Zhao. After the treatment of systemic drugs, the patient's lesions have improved significantly, and they are transferred to the family radiotherapy of radiotherapy.

On the morning of September 5, as the first patient to use the device, Mr. Zhao seemed to be particularly at ease. Lying in the spacious and bright treatment room, the entire radiation treatment process only takes 5 minutes, saving two -thirds from the 15 -minute treatment time required by the accelerator in the past, and the accuracy is also improved.

Professor Wang Hui, deputy dean of the hospital, introduced that this time the introduction of advanced medical linear accelerators is still the first station in Hunan Province. Compared with the traditional accelerator, it has four -dimensional visual image real -time guidance radiotherapy, SRS/SBRT three -dimensional directional radiation therapy, high high Dose rate irradiation (maximum dose rate can reach 2400mu/min), six -dimensional treatment bed, optical body surface tracking, active breathing control and other series of advanced treatment functions. High accuracy and short treatment time can give full play to its unique treatment advantages of fast, accurate and fierce.

It is understood that after the full load of the device is put into clinical application, 1,000 patients can be treated each year. The total number of people in the hospital can increase from more than 600 to more than 700 per day, which will significantly improve the overall service capabilities of tumor radiation therapy.
