Perform true spatial alignment and coincidence tests on IGRT systems

The QUASAR™ Penta-Guide Phantom is used for the commissioning and daily testing of Image-Guided Radiotherapy (IGRT) systems. The QUASAR™ Penta-Guide Phantom ensures the accuracy of linac-mounted image guidance systems, including cone beam CT (CBCT), x-ray volumetric imaging (XVI) and on-board imaging (OBI).

Minimize imaging artifacts by making use of the Penta-Guide's low-density objects to allow for rapid and easy daily testing of:
  • 3D cone beam registration
  • kV and MV system coincidence
  • kV and MV projection images
  • Laser and light field coincidence
  • Remote table adjustments

Simultaneous Testing

Ideally, one QUASAR™ Penta-Guide Phantom should be used per linac allowing simultaneous system testing and preventing unnecessary start-up delays.
