NCIRF: National Cancer Institute dosimetry system for Radiography and Fluoroscopy
NCIRF features state-of-the-art pediatric and adult computational human phantoms developed by the University of Florida and National Cancer Institute, representing reference individuals defined by the International Commission on Radiological Protection (ICRP). The phantom library will be extended to include the ICRP reference phantoms, the body size-dependent phantom library, and pregnant women phantoms.
On-the-Fly Monte Carlo Calculations
Interventional fluoroscopy often involves x-ray irradiation at various angles, even in a single session. Dose estimation based on pre-calculated dose tables may provide substantial dosimetric errors. Therefore, it is crucial to calculate organ dose using on-the-fly Monte Carlo radiation transport techniques. A 3D Monte Carlo, dose calculation module, based on an extensively benchmarked Monte Carlo code, GEANT4, is built in NCIRF and running in the background.
Intuitive User Interface
NCIRF provides an intuitive graphical user interface allowing users to select from various pediatric and adult computational phantoms and enter x-ray source definition, and finally to output organ doses with statistical errors. NCIRF is running on a personal computer, but users also can export input files running directly on a general-purpose Monte Carlo code, MCNP, to utilize their parallel computing servers. NCIRF also features a batch module where users can automatically run many radiation events.
