摘要:
近几年来,虽然放疗技术有了很大的提高,但是对随呼吸运动的病灶的适形放疗还不能令人满意,所以就出现了一些对呼吸进行补偿的方法,呼吸门控就是其中之一。目前虽然可以通过内部和外部标记对胸腹部病灶进行门控放疗,但是很明显内部标记与肿瘤病灶的实时运动一致性较好,而外部标记与胸腹部病灶的一致性并不完全相同:在腹部一致性较好,而胸部则较差。应用这些门控方法后,可以在一定程度上补偿呼吸对病灶的影响,精确靶区的勾画,减少可能出现的放疗副反应。
Abstract:
In recent years, radiotherapy techniques had been improved significantly, but it is still not so satisfied in the conformal treatment of the lesions that affected by respiratory movement. Respiratory gating is one of the several methods that can compensate the movement of tumors that caused by respiratory. Although both internal and external markers can be used in the gating radiotherapy, it is obvious that internal markers and tumors have good consistency, while external markers and tumors have different consistency:more consistent in abdomen than in thorax. After applying these gating methods, we can compensate the influence of respiratory, delineate the target volume more accurately, and reduce the potential adverse reactions of radiotherapy.
