AlignRT’s stereotactic calibration module allows clinics to deliver the benefits of frameless, open-mask SRS and SBRT / SABR using SGRT. To deliver the accuracy required for SRS, both an open face mask (supplied by various companies) and the SRS calibration cube (supplied by Vision RT) are required. The Head Adjuster is an option to enable SRS for facilities with no couches with 6 degrees of freedom.
The module enables a range of quality assurance tests – TG142 (linear accelerator) and TG147 (non-radiographic imaging).
Tests include: End-to-end localisation assessment, hidden target testing, localisation displacement accuracy, imaging coordinate coincidence across modalities, imaging positioning / repositioning, laser alignment, Winston-Lutz, couch rotation isocenter accuracy
