The purpose of this study is to develop a new setup method of radiotherapy using augmented reality which can match the CT images and the three-dimensional surface images acquired from the patient in the treatment room of radiotherapy.A pelvic or head phantom phantom was scanned by a CT scanner, and used as a reference planning CT image. Range images of the phantom with several different positions, which were considered as setup errors, were acquired by a time-of-flight (ToF) camera. The range images were registered with the planning CT images using an iterative closest point (ICP) algorithm, and position errors were calculated. This study suggested that patient setup errors could be visually monitored with the errors less than 2 mm by using range images acquired via a time-of-flight (ToF) camera.

本研究的目的是开发一种新的利用增强现实技术的放疗设置方法，该方法可以匹配放疗治疗室中患者的CT图像和三维表面图像。采用CT扫描骨盆或头部幻肢，作为参考规划CT图像。利用飞行时间（ToF）相机获取了幻影在不同位置的距离图像，这些图像被认为是设置误差。采用迭代最近点（ICP）算法将距离图像与规划CT图像进行配准，并计算位置误差。本研究表明，通过使用飞行时间（ToF）相机获得的距离图像，可以直观地监测患者的设置误差，误差小于2 mm。
