CT scan test phantom QUASAR™ Penta-Guide

general purpose

The QUASAR™ Penta-Guide Phantom is recognized globally as the preferred tool for commissioning and daily testing of Image-Guided Radiotherapy (IGRT) systems. The QUASAR™ Penta-Guide Phantom ensures the accuracy of LINAC-mounted On-Board Imaging (OBI) guidance systems, including KV, MV, and X-ray Volumetric Imaging (XVI) using Cone Beam CT (CBCT). Its simple and innovative design facilitates intuitive verification of spatial alignment and isocenter coincidence on IGRT and SGRT systems. The addition of an optional Penta-Guide Tilt-Plate provides intuitive verification of 6DoF couch adjustments. Combined with our included analysis software, Penta-Guide provides detailed image quality metrics that evaluate the performance of your CBCT imaging systems. Features Intuitive Design QUASAR Penta-Guide’s simple design promotes efficient daily testing to ensure on-board imaging alignment accuracy. The phantom contains a unique system of low-density rings and hollow spheres, enabling intuitive quality assurance while eliminating high-density imaging artifacts. Workflow Efficiency Integrate the QUASAR Penta-Guide IGRT phantom into your daily QA routine to perform geometric accuracy tests. Confirm room laser and IGRT targeting accuracy while simultaneously acquiring valuable CBCT image quality data to monitor On Board Imaging performance. Precision Manufactured to provide 0.25 mm accuracy – guaranteeing a high-calibre tool for your daily QA processes. Perform multiple isocenter coincidence and alignment tests with reliable repeatability and confidence. Visual tolerance features provide accurate determination of pass/fail criteria.
