作为目前世界上最先进的肿瘤放疗手段,粒子治疗特别是质子治疗有望在未来20~30年成为主流的放疗手段。近些年来,粒子治疗产业在发达国家发展非常快,每年都有数个质子中心投入使用。我国的粒子医疗产业也已进入快速发展期。粒子治疗中心一般包括质子中心、重离子中心和质子重离子中心。基本治疗原理是,使用加速器加速质子或重离子,使其以极高速度进入人体,抵达肿瘤部位时突然减速并释放大量能量,从而 As the most advanced tumor radiotherapy in the world, particle therapy, especially proton therapy, is expected to become the mainstream radiotherapy in the next 20 to 30 years. In recent years, the particle therapy industry has developed very fast in developed countries and several proton centers are put into use every year. China’s particle medical industry has also entered a period of rapid development. Particle treatment centers generally include proton centers, heavy ion centers and proton heavy ion centers. The basic principle of treatment is to use accelerators to accelerate protons or heavy ions into the body at very high velocities and suddenly decelerate and release large amounts of energy when they reach the tumor site
