MultiMet-WL Cube​


As clinics move toward single-isocenter multiple-met SRS treatments, more stringent off-axis QA is needed. The MultiMet-WL Cube efficiently measures targets up to 7 cm off-axis within 0.1 mm accuracy.

Six Isocenters for MultiMet QA
The MultiMet-WL Cube uses six targets set at precise locations from isocenter to measure off-axis and rotational gantry, collimator, and couch errors.

Off-Axis WL Tests, Fast
Complete six off-axis Winston-Lutz tests in the time it would normally take to complete just one. Automated software and an optimized RT plan enable fast and clinically useful analysis of the combined W/L results.

Versatile Small-Field Tool
Use as a standalone phantom or combine with the StereoPHAN™ and SRS MapCHECK® for an end-to-end stereotactic QA program.
