MRI test phantom RW3

for CT scanfor radiation therapyfor MR guided radiation therapy

Overview
RW3 Solid Water Standard Phantoms replicate human soft tissue accurately to deliver reproducible results for QA, commissioning and dosimetry in radiotherapy workflows. The homogeneous RW3 material provides a stable reference for photon and electron beam calibration and long-term dose verification.

Key product features

• Tissue-equivalent RW3 material with verified water-equivalence for dosimetry
• Modular phantom systems: EASY SLAB, EASY CUBE, and interchangeable head/body/oval/cylinder segments
• MR-compatible and MR-conditional variants specified up to 3T where applicable
• CE/MDR-compliant and FDA-ready documentation for clinical and OEM deployment
• Custom adapter plates and inserts for ion chambers, diodes, TLDs, EPIDs and films
• CT-based homogeneity verification for each unit prior to shipment
• Long-term radiation and mechanical stability to minimize density drift and surface changes

Advantages and benefits

• Verified tissue equivalence (density ~1.045 g/cm³) to ensure reproducible dose readings across detectors and setups
• Radiation-stable material for repeated QA and calibration cycles
• Modular design supports a wide range of QA geometries and detector alignments
• OEM integration options with custom adapters, inserts and traceable documentation
• Compatibility with common QA detectors: ion chambers, diode detectors, TLDs, EPIDs and radiosensitive films

Applications

• Routine QA: absolute dose checks and beam flatness/uniformity verification
• TPS commissioning: validation and benchmarking of treatment planning data
• End-to-end testing: imaging-to-delivery workflow verification
• Detector calibration: ion chamber and diode validation
• OEM system testing and integration with configurable phantom setups

Modular product family notes
EASY SLAB is a modular slab phantom system optimized for routine dosimetry. Constructed from homogeneous RW3 material, it supports absolute dose checks and dose distribution verification. Dedicated adapter plates enable sub-millimeter detector positioning. Available slab sizes: 300 × 300 and 400 × 400 mm; thickness options: 1 mm, 2 mm, 5 mm, 10 mm, 20 mm and 60 mm.

EASY CUBE supports end-to-end QA and imaging validation with modular segments (head, body, oval, cylinder) and configurable detector integration; suitable for commissioning and advanced QA workflows.
