Winston Lutz Cube Phantom (supported with PIPSpro Software) Precise QA for Stereotactic Radiosurgery

Expedite and simplify verification of sub-millimeter treatment setup.

Winston Lutz Cube Phantom (supported with PIPSpro Software) Overview

Simple IGRT QA

The Winston- Lutz Cube Phantom’s unique design includes offset alignment targets on 4 sides, making this phantom ideal for testing your system’s ability to apply corrective couch shifts for 2D MV/kV planar imaging and 3D CBCT.

  • Easily adjustable 6 cm x 6 cm cube for precise positioning
  • Offset alignment fiducial targets on 4 sides
  • 5 mm tungsten carbide sphere
  • White with black crosshairs for easy alignment to either light field or lasers
  • MV/kV isocentricity
  • 3D Cone Beam shifts

Quick, Comprehensive Stereotactic QA

A common QA procedure to verify isocenter for stereotactic radiosurgery is the Winston-Lutz Test. The Winston-Lutz Cube Phantom combines ball marker alignment and phantom-based laser alignment allowing quick verification of radiation isocenter and laser accuracy verification of pretreatment during this test, allowing for easy execution of all necessary stereotactic QA procedures.
