The AlignRT® Stereotactic Calibration Module enables clinics to deliver the benefits of frameless, open-mask SRS (stereotactic radiosurgery) and SBRT/SABR (stereotactic body radiotherapy) using SGRT (surface-guided radiation therapy).
To achieve the accuracy required for SRS, both an open mask (provided by several companies) and the SRS calibration cube (provided by Vision RT) are required. The module allows for a variety of quality assurance tests—TG142 (linear accelerator) and TG147 (non-radiographic imaging).
Tests include: edge-to-edge localization assessment, hidden target testing, localization shift accuracy, image coordinate matching between modalities, image positioning/repositioning, laser alignment, Winston-Lutz, stretcher rotation isocenter accuracy.
