Article Title: Characteristics of breathing-adapted gating using surface guidance for use in particle therapy: A phantom-based end-to-end test from CT simulation to dose delivery.
Article Snippet: These strategies include (i) expanding the internal margin of the target volume using the internal target volume (ITV) concept,21,22 (ii) utilizing abdominal compression to restrict the tumor motion (e.g., in liver treatments),23 (iii) employing breath-hold methods,23,24 (iv) implementing tumor tracking,24,25 and (v) using breathing-adapted gating approaches to attempt tracking the patient breathing, and irradiating the tumor target during specific breathing phases.26–32 For the latter, four-dimensional computed tomography (4DCT) is used to reconstruct images at specific breathing phases based on either amplitude or phase.28,33–36 Different respiratory monitoring systems (RMSs) are used for both 4DCT imaging and gating, including pressure sensors, skin-surface camera systems, radiofrequencybased systems and fiducial markers in combination with image-guided RT.23,37–41 At Heidelberg Ion Beam Therapy Center (HIT), three optical surface-guided RT (SGRT)38 systems, the AlignRT, SimRT, and GateRT (VisionRT Ltd, London, United Kingdom) have been installed between 2019 and 2021: (i) AlignRT and GateRT at the ion beam gantry treatment room, and (ii) SimRT at a CT scanner in the radiation oncology department.

Article Title: Optical surface information‐based respiratory phase‐sorting and motion‐incorporated reconstruction for SPECT imaging
Article Snippet: Newly developed optical surface imaging (OSI) systems, such as AlignRT (VisionRT, London, Great Britain) and Catalyst (C‐Rad, Uppsala, Sweden), have been introduced in external beam radiation therapy.

Article Title: Optical surface information-based respiratory phase-sorting and motion-incorporated reconstruction for SPECT imaging.
Article Snippet: Newly developed optical surface imaging (OSI) systems, such as AlignRT (VisionRT, London, Great Britain) and Catalyst (C-Rad, Uppsala, Sweden), have been introduced in external beam radiation therapy.17 These systems enable continuous and touchless scanning of patients’ external surfaces, and several studies have shown clear correlations between external surfaces and internal structures.18,19 Moreover, implementing this method does not require purchasing expensive equipment, a depth camera alone is sufficient.

Article Title: Exploring stereotactic radiosurgery for tremor using the Varian cone planning system.
Article Snippet: A phantom-based system was used to determine the optimal treatment delivery parameters for SRS tremor treatment, with imaging by Optical Surface Monitoring System (OSMS), (VisionRT, London, UK, www.visionrt.com) and CBCT/kV/portal images.

Article Title: Margin derivation from intrafraction patient motion of multi‐target, single isocentre, brain stereotactic radiosurgery treatments
Article Snippet: All brain SRS treatments were monitored in real‐time with AlignRT, an optical surface monitoring system (OSMS) from Vision RT (Vision RT Ltd. Dove House Arcadia Avenue, London N3 2JU, UK), which offers sub‐millimeter monitoring accuracy.

Article Title: Impact of deep inspiration breath hold, surface-guided radiotherapy, and daily CBCT on the organs at risk in breast cancer radiotherapy
Article Snippet: .. Studies have shown that patient setup accuracy using daily online verification with kilovolt cone-beam computed tomography (kV-CBCT) scans is significantly better compared to SGRT using optical surface monitoring systems (e.g., AlignRT, VisionRT Ltd, London, UK; C-RAD, Uppsala, Sweden), and SGRT is significantly better than the conventional technique of matching three orthogonal in-room laser beams with patient skin marks , . ..
