The Winston Lutz Cube is a quality assurance phantom designed for Winston-Lutz tests in stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT).
It enables precise verification of the isocenter defined by the gantry, collimator, treatment couch, and lasers. Manufactured with high accuracy, it ensures reliable reproducibility and simplifies alignment checks of rotational axes.
With its central tungsten-carbide insert aligned with fiducial markers visible on multiple sides, the cube provides quick and precise verification without requiring films or complex assemblies.
