Features
Intuitive Design
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
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
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.

Software
Included with every Penta-Guide Phantom is a software package designed to improve the Radiation Therapist (RT) and Physics QA analysis workflow. An emphasis on user-focused software features such as an RT QA checklist, automated image analysis, and performance trending, creates a time-saving and valuable quality assurance system.
Compatible with QUASAR DICOM Server.
Alignment Consistency
Early detection of system alignment problems can be achieved by monitoring the isocenter and on-board imaging performance. Use automated software analysis of imported images or manual daily shift entries to track system trends.
Image Quality Analysis
Use Penta-Guide’s automated analysis software to evaluate image quality metrics and monitor the performance of your LINAC OBI systems. Stats including spatial resolution, Houndsfield unit constancy and noise/contrast ratio can be used to trend CBCT performance.
Daily QA Checklist
Store and track daily QA results with simple pass/fail criteria using the integrated checklists. Designed to improve morning QA workflow for Radiation Therapists, these tools offer the ability to manage all daily QA data in one place.
Visualization Tools
Advanced 2D/3D visualization portal for the analysis of imported data provides a clear visual representation of system performance. Includes the ability to create line profiles and histograms of user-specified ROIs.
Reporting Feature
Penta-Guide software improves clinical workflow by creating custom reports of daily QA procedures. This provides a simple solution for users to communicate daily testing results to the Physics QA team.
