For regular quality assurance in radiation therapy

EASY CUBE – multi-modular QA phantom


Straightforward handling

The cube phantom's universal application possibilities simplify quality assurance. No additional tools are required. The multicolored grid on the cube surface allows precise alignment at CT or LINAC.

Variable adaptation

Adapters for your ionization chambers are available for dose measurement. Inhomogeneous inserts, stereotactic localizer plates and other elements allow perfect adaptation to the specific QA task. 

Modular expansion

In addition to the basic body, three additional designs are available. Different regions of the body, such as head, neck, and torso, can thus be optimally simulated. The extensions are modular to ensure an efficient workflow.
