2016-03-06 MedSci MedSci原创

粒子刀是集核物理学、放射生物学、肿瘤放射学、计算札应用等多门类学料于一体的高新技术产品,是面向二十一世纪最适合中国国情的内放疗设备。 粒子刀又称主体定向内放射治疗系统,它是在CT、MR、X光或B超导引下,通过治疗计划系统(TPS)制定治疗方案,计算出有效等剂量区及应植入的粒子数量,通过手术或经皮穿刺永欠性植入碘粒子。近20年来,由于新型、低 能核素,如碘-125、钯-103相继研制成功,计算机三维治疗计划系统的出现和超声、CT引导系统的发展使粒子治疗焕发了青春。放射性粒子组织间近距离 治疗肿瘤具有精度高、创伤小和疗效肯定等优势,临床应用显示了广阔的前景。
