Abstract

一种利用放疗设备确定目标靶点位置的方法、装置和放疗设备，涉及医疗领域，以准确的检测肿瘤位置的运动。放疗设备包括射线源(1)以及接收射线源(1)发出的射线的探测器(3)，利用放疗设备确定目标靶点位置的方法包括：射线源(1)位于第一位置(11)处，发出放射束(S101)；探测器(3)接收射线源(1)在第一位置(11)发出的射束，并根据接收的射束生成目标靶点的第一图像数据(S102)；射线源(1)运动至第二位置(12)处，发出放射束，其中，射线源(1)从第一位置(11)运动至第二位置(12)的间隔时间为患者的预设呼吸周期的正整数倍(S103)；探测器(3)接收射线源(1)在第二位置(12)发出的射束，并根据接收的射束生成目标靶点的第二图像数据(S104)；根据第一图像数据和第二图像数据，确定目标靶点的位置信息(S105)。
