Features of Gafchromic® XR-RV2 Film
• Coated on an opaque, white base with a yellow filter and viewed in reflection like a printed photograph
• 14” x 17” size radiochromic dosimetry film for measuring and mapping patient skin exposure during fluoroscopically guided procedures
• Self-developing, no post exposure processing, no waste disposal issues
• Can be handled in room light, eliminates need for darkroom
• Assures facility compliance with 1994 FDA advisory on patient exposure measurement and documentation
• Removes the uncertainty of dose estimation
• Shows the maximum dose and its location
• Shows how the total dose was distributed
• Provides a quantitative record for patient files
• Provides physician with guidance to enable safe planning of future fluoroscopically guided procedures
• Improves fluoroscopic technique and patient safety
• Color and optical absorbance changes in proportion to absorbed dose
• Dynamic range 1Gy to 50Gy
• Outstanding uniformity
• Minimal energy dependency from about 30keV to 30MeV, dose rate independent
• No dose fractionation effects
• Quantitative measurements with densitometer or scanner
• Rapid semi-quantitative evaluation with visual color comparison chart
• Shelf life: 18 month at room ambient temperature
It is recommended to use the comparative strip with XR-RV2.
GAFCHROMIC® XR-RV2 radiochromic dosimetry films have been developed for both the measurement of absorbed dose of low energy and high energy photons. It is sensitive to photons with energies between 30KeV and 30MeV thus sensitive over a wider energy range than its predecessor XR-R. However the principle goal remained the same and that is to provide dosimetry film media that can be used to measure patient skin dose in interventional procedures guided by fluoroscopy. For this reason, the product has been designed to have minimal dependence on photon energy over a wide range. GAFCHROMIC® XR-RV2 radiochromic dosimetry film is a reflective film.
