Summary:It is determined (402) that an element of a radiation therapy machine is to be moved to a respective target location therein (e.g., prior to starting a treatment of a patient). Candidate paths are defined and accessed (404), the candidate paths describing movement of the elements from the respective initial positions to the respective target positions. The candidate path is evaluated (406) to determine whether it will cause a collision between any of the elements. When the candidate path does not cause a collision between any of the elements, the candidate path is included (408) in a set of candidate paths. A value of a metric (e.g., an efficiency metric) for ranking each candidate path in the set of candidate paths is determined (410). A path is selected from the set of candidate paths based on the ranking (412). 确定(402)(例如，在开始患者的处置之前)要将辐射治疗机器的元件移动到其中的相应目标位置。限定并且访问(404)候选路径，候选路径描述元件从相应初始位置到相应目标位置的移动。对候选路径进行评估(406)以确定它是否将导致元件中的任何元件之间的碰撞。当候选路径不会导致元件中的任何元件之间的碰撞时，将该候选路径包括(408)在候选路径集合中。确定(410)用于对候选路径集合中的每个候选路径进行排
