Which QA tests can be done using the SRS Module?

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.

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.
