    Abstract: A patient positioning system for a radiation therapy system (100). The positioning system includes multiple external measurement devices (124) which obtain position and orientation measurements of components of the radiation therapy system (100) which are movable and/or are subject to flex or other positional variations from nominal. The external measurements provide corrective positioning feedback to more precisely register the patient and align them with the delivery axis (142) of a radiation beam. The positioning system monitors the relative positions of movable components of the radiation therapy system and plans an efficient movement procedure when indicated. The positioning system also plans the movement to avoid collisions either between the components of the radiation therapy system (100) as well as with personnel that may intrude into a movement envelope. The positioning system can be provided as an integral part of a radiation therapy system (100) or can be added as an upgrade to existing radiation therapy systems ( Fig. 1A ).

    Abstract translation: 一种用于放射治疗系统（100）的患者定位系统。 定位系统包括多个外部测量装置（124），该外部测量装置（124）获得放射治疗系统（100）的部件的位置和方位测量，其可移动和/或经受挠曲或其他与标称位置的变化。 外部测量提供校正定位反馈以更精确地对准患者并将其与辐射束的传送轴线（142）对准。 定位系统监测放射治疗系统的可移动部件的相对位置，并在指定时计划有效的运动程序。 定位系统还规划运动以避免辐射治疗系统（100）的组件之间的冲突以及可能侵入运动信封的人员。 定位系统可以作为放射治疗系统（100）的组成部分提供，或者可以作为现有放射治疗系统的升级而被添加（图1A）。

    Abstract: A device (100) which facilitates the closure of puncture wounds in the vasculature of a patient is used in conjunction with a guidewire, and helps locate and isolate the site of the puncture wound in the patient. The retractor (100) moves the surrounding tissue laterally when positioned in the patient, and acts as a guide for the physician in locating the exact site of the wound. A double-sleeved balloon can be used in conjunction with the retractor (100) to move the tissues laterally and form a tunnel from the surface of the patient's body to the puncture site. The retractor (100) is preferably used in combination with a surgical clip applicator which delivers clips to the site of the wound, but can also be used with other methods of wound closure such as suturing and stapling.
