Article Snippet: The SGRT system commissioned at our institution (Beijing Cancer Hospital, China) is the AlignRT (VisionRT Ltd, London, UK) as show in Fig. . A previous phantom-based study by Zhou et al. [ ] evaluated the motion detection accuracy and isocenter congruence of the AlignRT system, finding that the system was able to identify sub-millimeter and sub-degree shifts and that the isocenter deviation with CBCT was negligible.

Figure Lengend Snippet: Three major commercial OSI systems are used for SGRT applications in radiotherapy clinics. (A) AlignRT Advanced system, (B) Catalyst+ HD system, and (C) IDENTIFY system. The top row shows the cameras (and projector) in the pod and the bottom row shows the 3-pod OSI systems installed in the treatment room. Note that Varian’s IDENTIFY system has a 4th TOF camera pod above the couch.

Figure Lengend Snippet: Illustration of AlignRT torso surface images of a male (A and C) and a female subject (B and D) acquired using the AlignRT system. The volume of interest is defined between the 2 vertical lines (green), tilted horizontal line (purple), and anterior surface (A and B). Using the full-exhalation torso surface image as the reference, the torso volume changes are calculated for OSI-based spirometry. The 3D surface views are shown in (C and D) with 3 cutting planes: the tiled horizontal plane, and the 2 vertical planes along the edge of the rib cage to separate the thoracic and abdominal motions. The images are taken from the references (Li, et al. 2015b; Li, et al. 2016b) with permission.
