    • Systems, methods, and apparatuses are provided for targeting diseased tissue with a radiation beam. Functional models can be used to accurately obtain a location of specific tissue using sensors at identifiable locations of the patient's body. Using the relative distances between the identifiable sensor locations can allow a patient to be in various positions. The functional models can be prepared using accurate pre-treatment scans, which can be taken at various body positions (e.g., rotations and/or translations). The trajectory of the beam can be measured efficiently and accurately using beam sensors attached to a beam assembly, where a model maps the beam sensor locations to a trajectory of the beam. Further, a motion model can use measurements made during treatment to obtain a time-dependent functions of the movement of the specific tissue, the change of an optimal beam trajectory over time, or the change in input commands to a beam positioner.
    • 提供了用辐射束靶向患病组织的系统,方法和装置。 功能模型可以用于在患者身体的可识别位置使用传感器精确获得特定组织的位置。 使用可识别的传感器位置之间的相对距离可以允许患者处于各种位置。 可以使用精确的预处理扫描来准备功能模型,其可以在各种身体位置(例如,旋转和/或翻译)下进行。 可以使用连接到光束组件的光束传感器来有效和准确地测量光束的轨迹,其中模型将光束传感器位置映射到光束的轨迹。 此外,运动模型可以使用在治疗期间进行的测量来获得特定组织的运动的时间相关函数,随时间的最佳波束轨迹的改变,或者输入命令的变化到波束定位器。
