Winston Lutz Phantom

Expedite and simplify verification of sub-
millimeter isocenter treatment setup.

Quick, Comprehensive Stereotactic QA

Facilitates ball marker alignment with the laser-described isocenter for easy execution of all necessary stereotactic QA procedures.

Go Filmless with PIPSpro Software

PIPSpro Comprehensive Software, when coupled with the Winston-Lutz Pointer Phantom, uses your portal imaging system to acquire images of the ball marker. This determines the 3D stand offset and provides isocenter measurements within 0.1 mm.

Features & Benefits

Minimize isocenter displacements

Lightweight and easy to use phantom with micrometer X, Y, and Z axis adjustments for fine tuning positioning of the Winston-Lutz Pointer Phantom. Making accurate fine adjustments, such as the shifts calculated by the PIPSpro stereotactic module, are impossible without the aid of micrometer adjustment stages. This product is intended to enable users to make accurate sub-millimeter shifts in each of the three axes.

Submillimeter adjustments

  • 0.01 mm scale resolution along each axis of the micrometer stage.
  • Travel distance of ± 6.5 mm along each axis.
  • Independent X, Y, and Z axis adjustment to ensure isocenter alignment.
  • Lock down to couch at isocenter instantly to prevent shifting of the base while micrometer shifts are being applied.
  • Three pin fine leveling and bubble level adjust pointer to match laser lines for easier setup.

Winston Lutz Pointer Phantom

  • Easily adjustable for precise positioning
  • Carbon fiber rods ensure stability once positioned
  • 5mm tungsten carbide sphere
  • White on black and black on white lines for easy alignment to either light field or lasers
