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.
