Winston Lutz Cube Phantom (supported with PIPSpro Software) Overview

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.
