Abstract

一种肿瘤位置的追踪方法及放射治疗设备(100)，涉及医疗器械技术领域，解决现有肿瘤位置追踪的准确性和可靠性较低的技术问题。一种肿瘤位置的追踪方法，应用于放射治疗设备(100)，所述放射治疗设备(100)包括至少一个射线源(10)以及第一探测器(20)，包括：射线源(10)发出预定强度的射线束，所述射线束穿过人体病灶后部分散射发出(S101)；所述第一探测器(20)接收所述散射的部分射线束，以获取所述病灶的散射数据(S102)；根据获取的所述散射数据确定病灶与靶区的相对位置关系(S103)；根据确定的所述相对位置关系，调整下一周期射线束强度、病灶位置和靶区位置中的至少一个，使得下一周期所述病灶在靶区位置接收预定强度的射线束的照射(S104)。
