Title: INTEGRATED SYSTEM SIMULATION IN X-RAY RADIOGRAPHY

An integrated simulation capability is being developed to examine the fidelity of a dynamic radiographic system. This capability consists of a suite of simulation codes which individually model electromagnetic and particle transport phenomena and are chained together to model an entire radiographic event. Our study showed that the electron beam spot size at the converter target plays the key role in determining material edge locations. The angular spectrum is a relatively insensitive factor in radiographic fidelity. We also found that the full energy spectrum of the imaging photons must be modeled to obtain an accurate analysis of material densities.
