伽玛刀的分代特征与选购要点

The Generation Characteristics and Purchasing Points of Gamma Knife

随着计算机技术的飞跃发展和放射治疗设备的不断更新,最新一代的伽玛刀放射治疗系统与最初的伽玛刀放射治疗系统已有巨大地显著区别。不仅在功能上不断完善,而且治疗的适应证也在不断扩展,突破了肿瘤外科的许多手术禁区,挽救了大批因解剖关系而不能进行手术治疗的肿瘤病人,其中也包括了部分良性病变的患者。但是时至今日,仍有许多学者对伽玛刀放射治疗系统的诸多功能和分代特征并不十分清楚,再加上各生产厂家对外宣传的不同引导,致使伽玛刀放射治疗系统的许多概念和分代特征存在着混乱,特别是在购置该治疗设备时更是显得无所适从。为此,笔者就近年来各厂家生产的伽玛刀放射治疗系统的特征作以综述,其目的是给各购置单位和专家提供部分可供参考的依据。

With the rapid development of the computer technology and the constant updating of the radiotherapy equipment, a huge improvement has been manifested by the new generation of the Gamma Knife radiotherapy system. Not only its functions are being improved, but also the treatment indications are expanding. These advances have been widely recognized by the clinical medical experts, breaking off the forbbiden zone of surgical operations, saving a lot of tumor patients with both malignant and benign lesions, who are not suitable for surgical operations due to local anatomical limitations.
