Radiation therapy test phantom QA

for PET and SPECTfor tomographyfor MR guided radiation therapy

Overview
Customized QA tools from gKteso combine OEM-specific design with tissue-equivalent Solid Water (RW3) and radiation‑hard materials to provide accurate, reproducible QA and dosimetry results for radiotherapy and medical imaging. Products are developed for integration from prototype to serial production and delivered with CE/MDR and FDA-ready documentation for QA, calibration and clinical validation.

Advantages and benefits

• OEM-specific design and scalable local manufacturing for QA, calibration and R&D
• Tissue-equivalent Solid Water (RW3) for reproducible dose measurement and dosimetric stability
• OEM labelling and registration-ready designs for integration into vendor workflows
• Mechanical precision down to 0.02 mm to support high-precision alignment and setup reproducibility
• Short prototype cycles and low- to medium-volume serial production (single units to several hundred per year)
• Radiation‑hard polymers, adhesives and composites for long-term dimensional, visual and dosimetric stability

Applications

• LINAC commissioning: beam model validation and dose calibration
• Imaging QA (CT, MRI/IR, PET): cross-modality calibration and distortion detection
• Adaptive radiotherapy: QA for real-time correction and motion management systems
• Dosimetry and calibration: water-equivalent measurement and detector verification using RW3
• End-to-end QA: workflow validation from imaging to dose delivery including SGRT and MR-Linac processes
