Modern radiotherapy demands more quality assurance, more imaging verification, and more workflow confidence than ever before. Yet clinics are expected to achieve this with the same resources and increasing operational pressures.
The QUASAR® 1 Penta-Guide Performance Phantom brings together a wide range of machine and imaging QA workflows in a single, flexible phantom, helping clinical teams simplify daily QA, reduce setup complexity, and maintain confidence across modern radiotherapy workflows.
Daily QA optimization
The challenge
Modern radiotherapy demands more QA with the same resources. Multiple phantoms and repeated setups increase complexity, time and risk of error.
The solution
Combines imaging, geometry, mechanical and alignment verification in one streamlined workflow.
Treatment Delivery Confidence
- Geometric accuracy
- System Alignment
- Imaging Information
Built for Adaptive Radiotherapy
Verify image quality, geometry and imaging consistency to support adaptive radiotherapy workflows.
