Real-time X-ray dosimeter for patient radiology

• Instant acquisition of delivered X-ray dose on patient
• Can be positioned anywhere on the patient

TECHNOLOGY

• Plastic scintillators transmitting the signal by optical fibres
• Signal treatment by TCSPC (Time Correlated Single-Photon Counting)
• Measure of a wide range of X-rays (10 keV to 300 MeV)
• Dose rate from 0.1μGy/s up to>2mGy/s
• Can also measure charged particles & neutrons

APPLICATIONS

• Real-time clinical radiology
• Acquisition of X-ray doses delivered by any source
• Can be integrated to the patient bed or clothes

INNOVATION ADVANTAGES

• Very small detector, invisible on radiology
• Great sensitivity and excellent linearity of the acquisition
• Dose measured directly on the patient
• Easy to handle and to transport
• Adaptability to the dose and to the X-ray generator

DEVELOPMENT STATUS

• Proof of concept demonstrated on the prototype
• Miniaturisation (kg-scale)
• Assays performed on phantoms and patients in hospitals
